Coral Annabell Buttsworth (née McInnes; 7 June 1900 – 20 December 1985) was a female tennis player from Australia who won the singles title at the Australian Championships in 1931 and 1932 and the women's doubles title there in 1932.^[2][3] In 1933 she again made the final of the Australian Championships but was defeated in straight sets by first-seeded Joan Hartigan.^[4]

Buttsworth was the only multiple winner of the singles title at the Australian Championships who never won a state singles title. A strong, thick-set woman from Sydney, she was addicted to chopping the ball, with an excellent drop shot, and was quick around the court. She was a player who preferred to maneuver opponents out of position by running them up and back on the court rather than from side to side.^[3]
