Judy Tegart-Dalton AM (née Tegart; born 12 December 1937) is an Australian former professional tennis player.

Tegart reached the final at Wimbledon in 1968, where she lost to Billie Jean King in two tight sets after defeating second-seeded Court in the quarterfinal and third-seeded Nancy Richey in the semifinal.

Her last appearance at a Grand Slam tournament was the 1977 Australian Open, where at the age of 40 she lost in the quarterfinals in straight sets to top-seeded and eventual champion Evonne Goolagong Cawley.

[1] Tegart was unusual in that she did not reach the quarterfinals of a Grand Slam singles tournament outside of Australia until she was 29 years of age.

From Wimbledon in 1967 until the end of her career, she reached at least the quarterfinals in half of the Grand Slam singles tournaments she played (10 out of 20).
