In 1982, King began a comeback, winning the Wimbledon warm-up tournament the 1982 Edgbaston Cup in Birmingham, her first singles title in more than two years. King was 38 years old and the twelfth-seed at Wimbledon. In her third round match with Tanya Harford of South Africa, King was down 7–5, 5–4 (40–0) before Harford's apparent winner was deemed 'not up' by the umpire, something the South African protested vehemently. King then saved the next two match points to win the second set 7–6(2) and then the third set 6–3. King said in her post-match press conference, "I can't recall the previous time I have been so close to defeat and won. When I was down 4–5 and love–40, I told myself, 'You have been here 21 years, so use that experience and hang on. In the fourth round, King upset sixth-seeded Australian Wendy Turnbull in straight sets. King then upset third-seeded Tracy Austin in the quarterfinals 3–6, 6–4, 6–2 to become the oldest female semi-finalist at Wimbledon since Dorothea Douglass Lambert Chambers in 1920. This was King's first career victory over Austin after five defeats and reversed the result of their 1979 Wimbledon quarterfinal. King said in her post-match press conference, "Today, I looked at the scoreboard when I was 2–0 in the third set and the '2' seemed to be getting bigger and bigger. In 1979, when I was up 2–0 at the same stage, I was tired and didn't have anything left. But today I felt so much better and was great mentally." Two days later in the semi-finals, which was King's 250th career match at Wimbledon in singles, women's doubles, and mixed doubles, the second-seeded Chris Evert defeated King on her fifth match point 7–6(4), 2–6, 6–3. King was down a set and 2–1 in the second set before winning five consecutive games to even the match. King explained that she actually lost the match in the first set by failing to convert break points at 15–40 in the second and fourth games. Having started the year in retirement, King finished 1982 ranked 14 in the world.
