1979 Avon Championships

Main article: WTA Finals

The 1979 Avon Championships were the eighth WTA Tour Championships, the annual tennis tournament for the best female tennis players in singles and doubles on the 1979 WTA Tour. It was held on indoor carpet courts from March 21 through March 25, 1979, in Madison Square Garden in New York City, New York.

First-seeded Martina Navratilova won the singles title and earned $100,000 first-prize money.

For the first time since 1975, the doubles tournament at the WTA Finals was played separately from the WTA Doubles Championships which took place two weeks later in Japan, although by strange coincidence the final that year featured the same two pairings, the same outcome and almost the same scoreline (7–5, 7–6(9–7)).
