Ty Hubert Detmer (born October 30, 1967 in San Marcos, Texas), is an American football quarterback who starred at Brigham Young University and currently plays for the Atlanta Falcons.

Detmer attended Southwest High School in San Antonio, Texas. He earned letters in golf, football, basketball, baseball, and track. As a senior, he won All-America honors in football and was the Texas Player of the Year. He also won All-State honors in baseball and All-District in basketball. His father, Sonny, was his football coach.

While at Brigham Young University, Detmer had one of the most spectacular careers in college football history. He redshirted during the 1987 season, and shared quarterback duties with Sean Covey as a freshman in 1988. He started a game against New Mexico, and passed for 333 yards and 5 touchdowns in a 65-0 BYU victory. He was named Most Valuable Player of the 1988 Freedom Bowl, leading BYU to a come-from-behind 20-17 victory over Colorado.

Detmer became a full-time starter in 1989. He emerged as one of the top quarterbacks in the nation, passing for 4,560 yards and 32 touchdowns. His passing rating of 175.6 led the NCAA, and he finished second to Houston's Andre Ware in total offense. He led BYU to a WAC Championship, their first since 1985. Detmer finished the season with a strong performance against Penn State in the 1989 Holiday Bowl, setting NCAA records for most passings yards (576) and most yards of total offense (594) in a single bowl game.

Detmer's junior season (1990) was his best at BYU, and ranks as one of the greatest seasons for a quarterback in college football history. Detmer passed for 5,188 yards and 41 touchdowns, and finished the season with 42 NCAA records (and tied for five others). The highpoint of the season came in BYU's 28-21 upset victory over top-ranked Miami (FL); Detmer led the Cougars by passing for 406 yards and 3 touchdowns against the defending national champions. For his efforts, Detmer was awarded the Heisman Trophy, and received many other honors (including the Maxwell Award and the Davey O'Brien Award). He was named First Team All-America by the AP, UPI, Football Writers, Walter Camp, Football News, Scripps Howard, and the Sporting News. Unfortunately for Detmer and BYU, the season ended in nightmarish fashion, as the Cougars were routed in their final regular season game (59-28 against Hawaii) and in the 1990 Holiday Bowl (65-14 against Texas A&M). Detmer was knocked out of the game against Texas A&M, suffering two separated shoulders that required off-season surgery.

The 1991 season started poorly for BYU. With inexperienced teammates, Detmer could not get BYU's offense going, and Cougars lost their first three games (against Florida State, UCLA, and Penn State). After an 0-3 start, Detmer and BYU turned things around. The Cougars won eight straight games, and clinched their third consecutive WAC Championship with a spectacular 52-52 tie against San Diego State in their final regular season game. In that contest, BYU fell behind 45-17 before Detmer led a stunning comeback. He finished the game with 599 passing yards and 6 touchdowns, both career highs. In his final game as a Cougar, Detmer led BYU to a 13-13 tie against heavily-favored Iowa in the 1991 Holiday Bowl.

Detmer totaled 4,031 passing yards and 35 touchdowns in his senior season. He finished third in the Heisman Trophy voting, but did win the Davey O'Brien Award again and also earned the Sammy Baugh Award. He was named First Team All-America by several organizations. His final career statistics were mind-boggling: 1,530 pass attempts; 958 completions; 15,031 passing yards; 121 touchdown passes; 14,665 yards of total offense; all of these totals shattered NCAA records. In all, Detmer finished his college career with 59 NCAA records (and tied for three others).

Despite his success at BYU, Detmer was deemed too small to play quarterback in the NFL. The Green Bay Packers drafted him in the ninth round (230th pick overall) of the 1992 NFL Draft. Detmer spent four seasons with the Packers, but did not see much action while backing up Brett Favre.

Detmer found more playing time after signing a free agent contract with the Philadelphia Eagles in 1996. After Rodney Peete suffered a knee injury, Detmer became the team's starting quarterback. Detmer posted a 4-0 record in his first four starts. In his second start, he threw four touchdown passes (all to Irving Fryar) against the Miami Dolphins. The following week, he passed for a career-high 342 yards against the Carlolina Panthers. The next week, he passed for 217 yards and a touchdown and added his first career rushing touchdown against the Dallas Cowboys. It was Philadelphia's first victory at Dallas since 1991, and earned Detmer the Miller Lite NFL Player of the Week award. For the year, Detmer passed for 2,911 yards and 15 touchdowns; his 80.8 passer rating ranked fourth among NFC quarterbacks. The Eagles posted a 7-4 record with Detmer as the starter during the 1996 season.

The following season, he shared quarterback duties with Rodney Peete and Bobby Hoying. In 1998, he left Philadelphia and joined the San Francisco 49ers as a backup to Steve Young. He only spent one season in San Francisco; his lone start came against the Panthers. He passed for 276 yards and 3 touchdowns in the 49ers' 25-23 victory.

In 1999, Detmer was traded to the Cleveland Browns, who wanted him to mentor rookie Tim Couch. Detmer started the first two games of the 1999 season, then served as backup to Couch for the rest of the season. Detmer injured his right Achilles and was inactive the entire 2000 season.

Detmer spent three seasons (2001 to 2003) with the Detroit Lions. He started four games during the 2001 season. His first start was a disaster; he threw 7 interceptions against the Browns. He was eventually replaced as starter, but did start the final two games of the season. He set career highs for attempts (50) and completions (31) against the Chicago Bears, finishing with 303 passing yards. He closed out the season with 242 yards and 2 touchdowns against the Cowboys.

Detmer spent the 2004 season with the Atlanta Falcons, but did not see any action. He is currently the Falcons' third-string quarterback, behind Michael Vick and Matt Schaub.

In 14 total seasons in the NFL, Detmer has played in 54 games (with 25 starts), totaling 6,351 yards passing with 34 touchdowns and 35 interceptions.

Detmer's younger brother, Koy Detmer, currently plays for the Eagles, and has been with the team since his older brother Ty left the team.

Ty Detmer and his wife Kim have four daughters: Kaili (12), Aubri (9), Mayci (7), and Rylli (5).

Detmer graduated from BYU with a degree in recreation administration.
