The 1991 WTA Tour (officially titled 1991 Kraft General Foods World Tour after its sponsor) was the elite professional tennis circuit organized by the Women's Tennis Association (WTA) for the 1991 tennis season.

The WTA Tour is the elite tour for professional women's tennis organised by the Women's Tennis Association (WTA). The WTA Tour includes the four Grand Slam tournaments, the WTA Tour Championships and the WTA Tier I, Tier II, Tier III and Tier IV events. ITF tournaments are not part of the WTA Tour, although they award points for the WTA World Ranking.
