The following is a partial list of characters from the television series Grey's Anatomy: Template:Spoiler

• Dr. Meredith Grey: Meredith is the eponymous character of the series and her voice-over is usually the narration at the beginning and end of the show. Many people call in the 3rd season have called her "Dark and Twisty" and "Scary and Damaged". A graduate of Dartmouth College, she is the daughter of Ellis Grey, a renowned doctor and trailblazing female surgeon. Her father, Thatcher Grey, left the family when she was very young, maybe at the age of five, she was there at the time when Dr. Richard Webber ends his affair with her mother. As the show begins, we learn that Ellis has been stricken with a severe case of Alzheimer's Disease. Meredith now lives in her mother's home, which she shares with Izzie and George. In the first episode, Meredith sleeps with Derek Shepherd as a one-night stand, only to learn when she reports for her first day at Seattle Grace that Derek is a doctor and her boss. Their on-off relationship has continued throughout the series. She called herself the dirty ex-mistress. At one point Meredith also dates Finn, a vet, who vies for her love. At the prom she ends up having sex with Derek and is forced to choose between the two. She eventually chooses Derek.

• Dr. Cristina Yang: A doctor of Korean descent raised in Judaism (her mother converted on re-marriage) and a native of Beverly Hills, Los Angeles, Yang is not religious, but has mentioned Jewish customs from her upbringing like Shiv'ah and at times has referred to herself as Jewish. Her mother remarried three years after Cristina was born to Dr. Saul Rubenstein, an oral surgeon. She is incredibly focused and driven (even more so than the others) and is always excited about the chance to scrub in on a surgery. She is a graduate of Smith College, Stanford University medical school, and has a PhD from University of California, Berkeley. She became romantically involved with Dr. Burke; after she became pregnant, she kept the pregnancy a secret from him until she collapsed one day at work and learned she had an ectopic pregnancy, which had to be aborted. She loves Burke, but is somewhat reserved emotionally (she only told him she loved him while he was asleep). Though Cristina frequently shows technical proficiency, her personality can be harsh. She is a self-confessed slob.

• Dr. Isobel "Izzie" Stevens: Izzie is the blonde roommate of Meredith and George. She grew up in nearby Chehalis, Washington living in a trailer park, paying her way through medical school as an underwear model. When meeting a pregnant teenage girl from her hometown, she revealed that she had a daughter at 16 whom she subsequently gave up for adoption. Her daughter, Hannah, who is now eleven, was adopted by a presumably upper class family that once lived in Santa Barbara but has since moved; Izzie doesn't currently know where her daughter lives. Izzie has a history of becoming too emotionally involved with her patients, including Denny Duquette, who passed away in the second season finale -- after she accepted his marriage proposal. In this same episode, Izzie announces that she will be leaving the surgical internship program - her future is currently up in the air. In the third season, Dr. Bailey asks Izzie to stay in the program and she finds Duqette has left her a large inheritance, $8.7 million. She decides not to cash her multimillion dollar check until she knows what good can come of it.

• Dr. George O'Malley: One of Meredith's roommates, he formerly had an infatuation with Meredith which he only recently admitted, and ended up having a one-night stand with her. She cried during their encounter. Often the most emotional of the male doctors, he sometimes gets into arguments with others despite his more positive personality. He has a markedly different personality from those of his brothers, one of whom accidentally shot his father in the buttocks on a Thanksgiving hunting trip. He had one girlfriend before, a nurse named Olivia, from whom he contracted syphilis. He was dating Dr. Callie Torres, an orthopedic surgeon at Seattle Grace, but his poor treatment of her in the third season has led her to get some distance.

• Dr. Alex Karev: A former wrestler at the University of Iowa. Alex became a wrestler because his father used to beat his mother, Alex beat up his father after his father hit his mother. Alex's father ended up in the hospital and he left Alex and his mother after the incident. His father was a musician and was a drug addict. He had an on and off relationship with Izzie until she caught him sleeping with the nurse Olivia; they later got back together when Izzie had sex with him in a supply room in the midst of a bomb scare. But after Denny Duquette returns to the hospital with a failing heart, Izzie realizes that she doesn't have to settle for Alex. She says to Alex just before scrubbing in on Denny's LVAD surgery, "On your very best day, that corpse is twice the man you will ever be. You're not good enough for me, Alex. You're not good enough for anyone." Alex often tries to be a "macho" sort of character, and showed an interest in plastic surgery when a visiting surgeon discussed his career prospects in Seattle. However, Alex has shown signs of distaste with plastic surgery after serving as Dr. Sloan's intern. Alex prides himself on his honesty, which often lacks tact and can verge on being brutal. However, Alex does have a moral code and is the only doctor who tells the truth as it is.

• Dr. Miranda Bailey: A graduate of Wellesley College, Miranda Bailey is a resident surgeon who is also in charge of the five interns, Bailey earned the nickname "The Nazi" for her tough personality. She gave birth to son, William George Bailey Jones, during a bomb scare, while at the same time her husband, Tucker, was in surgery with Dr. Shepherd ("As We Know It"). She is currently adjusting to being a parent while at the same time handling her career.

• Dr. Calliope "Callie" Torres: An orthopedic surgeon who has a relationship with George O'Malley (first appearance: "What Have I Done to Deserve This?"). She lived in the basement of the hospital. She told George "I love you" ("17 Seconds") and later revealed that this was the first time she said that to a man. Webber found out she was living in the hospital and kicked her out ("I Am a Tree"). She temporarily moved in with O'Malley but he couldn't stand to live with her so she stormed out and moved into the Orchard Hotel. After she invites him to her hotel room one evening, but he stands her up to go to Izzie, at the bar Callie invites Mark up to her hotel room instead.

• Dr. Derek Shepherd: Head of neurosurgery at SGH, the interns have nicknamed him "McDreamy" for his good looks. He was in a relationship with Meredith beginning in the first season, but abruptly ended it when his estranged wife, Dr. Addison Forbes Montgomery Shepherd, arrived in Seattle. (He had left her behind in New York City after catching her in bed with his best friend, Mark Sloan.) He tried to work things out with Addison, but was infatuated with Meredith, though he vehemently denied it when questioned. He and Meredith had sex during the hospital prom and left Meredith's panties in his tux. When Addison discovered them, she called Mark Sloan, who came to Seattle in what he called a 'transcontinental booty call' ("I Am a Tree"). He left Addison and vied with Finn for Meredith's affection, before finally giving in and conceding Finn was the nicer guy. But Meredith ended up picking him, because he was The One.

• Dr. Preston Xavier Burke: The chief cardiothoracic surgeon at Seattle Grace. After completing pre-medical studies at Tulane University, Burke graduated first in his class from Johns Hopkins Medical School, not because he was necessarily the most talented nor the smartest, but because he worked the hardest. He was once the interim chief of surgery while Dr. Webber was healing from his own brain surgery. He began a relationship with intern Cristina but broke it off because he feared it would ruin both of their reputations. Her miscarriage brought them back together. He and Cristina now live together in his perfectly-kept apartment. In the second season finale he was shot, affecting his control of his right-hand.

• Dr. Richard Webber: The current Chief of Surgery at Seattle Grace. He had an affair with intern Meredith's mother, Ellis Grey (which he did not know his wife knew about). He is a recovered alcoholic ("Superstition"). His niece is dying of ovarian cancer. His wife, Adelle, asked him to retire, forcing him to choose between his career or their marriage. He moved out and was sleeping in his office for short time, but now has a room at the same hotel as Callie.

• Dr. Addison Forbes Montgomery (formerly Montgomery-Shepherd): A highly regarded neo-natal surgeon; while married to Derek, she had an affair with his best friend, plastic surgeon Dr. Mark Sloan, prompting Derek to leave New York for Seattle. Dr. Webber brings her to Seattle Grace for a consult on a difficult case and also to break things up between Derek and Meredith. Richard was aware of Derek and Addison's strained relationship, though not the cause of it ("Yesterday"). She decides to stay on as head of neonatal at Seattle Grace, signing a lucrative 2 year contract, and she and Derek decide to work things out. But when Derek has an affair with Meredith, she calls Mark Sloan to Seattle for an affair in response, and Derek leaves her. She asks Mark Sloan to go back but he stays, wanting to continue their relationship, but she continues to rebuff him. After the couple split, the former Shepherd couple finalized their divorce and she dropped the "Shepherd" from her last name.

• Dr. Mark Sloan: A top-tier plastic surgeon, he used to be Derek's best friend until he caught him in bed with his wife Addison. He professes his love to Addison and attempts to bring her back to New York; she refuses and stays in Seattle ("Yesterday"). Addison also reveals (by telling Derek) in this episode that after Derek left for Seattle, she and Mark continued their relationship until she caught him cheating on her and left. The interns have given him the nickname "McSteamy" (to compliment Derek's "McDreamy") for his rugged good looks. He flew out for sex at Addison's request ("I Am a Tree") and since got a job at the hospital.
