Judy Tegart Dalton (born 12 December 1937) is a retired professional Australian tennis player who won nine Grand Slam doubles titles. She won at least one women's doubles title at each Grand Slam tournament, a "Career Grand Slam". Five of her doubles titles were in partnership with Margaret Court. Dalton was the runner-up in ten Grand Slam doubles tournaments.
Dalton reached the final at Wimbledon in 1968, where she lost to Billie Jean King 9–7, 7–5 after defeating Court in a quarterfinal and Nancy Richey Gunter in a semifinal. She also reached the singles semifinals at Wimbledon in 1971 at the age of 33, losing to Court in three sets, and at the Australian Championships in 1968, losing to King in three sets. Her final Grand Slam tournament was the 1977 Australian Open, where at the age of 40 she lost to top-seeded and eventual champion Evonne Goolagong Cawley in a quarterfinal 6–3, 6–1.
Dalton 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 (ten out of twenty).
Dalton was a member of the Australian Federation Cup team in 1965, 1966, 1967, 1969, and 1970. Her career won-loss record was 18–4, including 6–1 in singles and 12–3 in doubles. Australia won the Federation Cup in 1965 and 1970.
Dalton was one of the original "Virginia Slims 9", the nine players who in 1971 joined the break-away Virginia Slims tour organised by Gladys Heldman. She married D. E. Dalton in 1969.
