The 1990 WTA Tour is the elite professional tennis circuit organized by the Women's Tennis Association (WTA) for the 1990 tennis season. The 1990 WTA Tour calendar comprises the four Grand Slam tournaments, the WTA Tour Championships and the WTA Tier I, Tier II, Tier III, Tier IV and Tier V events. ITF tournaments are not part of the WTA Tour, although they award points for the WTA World Ranking.
This is the complete schedule of events on the 1990 calendar, with player progression documented from the quarterfinals stage.
Below are the 1990 WTA year-end rankings (November 26, 1990) in both singles and doubles competition:
The Women's Tennis Association (WTA), founded in 1973 by Billie Jean King, is the principal organizing body of women's professional tennis. It governs the WTA Tour which is the worldwide professional tennis tour for women. Its counterpart organization in the men's professional game is the Association of Tennis Professionals (ATP).
The Women's Tennis Association was founded in the month of June 1973, but traces its origins to the inaugural Virginia Slims tournament, arranged by Gladys Heldman, and held on 23 September 1970 at the Houston Racquet Club in Houston, Texas. Rosie Casals won this first event. The WTA's corporate headquarters is in St. Petersburg, Florida, with its European headquarters in London and its Asia-Pacific headquarters in Beijing.
The Open Era, allowing professional players to compete alongside amateurs, began in 1968. The first open tournament was the British Hard Court Championships in Bournemouth. At the first Open Wimbledon the prize fund difference was 2.5:1 in favour of men. Billie Jean King won £750 for taking the title while Rod Laver won £2,000. The total purses of both competitions were £14,800 for men and £5,680 for women. Confusion also reigned as no one knew how many open tournaments there were supposed to be. The tournaments that did not want to provide prize money eventually faded out of the calendar, including the U.S. Eastern Grass Court circuit with stops at Merion Cricket Club and Essex county club.

The 2006 Sony Ericsson WTA Tour was the 34th season since the founding of the Women's Tennis Association. It commenced on January 2, 2006, and concluded on November 12, 2006 after 61 events.
Justine Henin-Hardenne came out as the winner in a historic three-way battle for the No. 1 ranking at the season-ending WTA Tour Championships, beating out Sharapova and Mauresmo. The Belgian successfully defended her French Open title for her fifth Grand Slam title, and became the first woman since Steffi Graf in 1993 to reach the finals of all four Grand Slams and the WTA Tour Championships. Maria Sharapova won her second Grand Slam title at the U.S. Open, to add to her Wimbledon trophy from 2004. Amélie Mauresmo won her maiden Grand Slam at the Australian Open after a controversial retirement from Henin-Hardenne in the final. However, she later backed it up by winning a rematch with Henin-Hardenne in the Wimbledon final. She was the number one player in the world from March until the final event of the season.
