The 1990 Texas gubernatorial election was held on November 6, 1990, to elect the governor of Texas. Incumbent Republican Governor Bill Clements did not run for re-election, so the election pitted Democrat Ann Richards against Republican Clayton Williams. Richards narrowly defeated Williams on Election Day, winning 49.5% of the vote to Williams' 46.9%. As of 2024, this is also the most recent time the Democratic candidate has carried Collingsworth, Childress, Wilbarger, Wichita, Archer, Throckmorton, Montague, Wise, Tarrant, Grayson, Lamar, Hopkins, Titus, Bowie, Harrison, Panola, Shelby, Jasper, Hardin, Angelina, Polk, Houston, Madison, Walker, Kaufman, Navarro, Henderson, Hill, McLennan, Williamson, Burleson, Waller, and Refugio counties. As of 2024, this is the last time a Democrat and a woman was elected Governor of Texas, as well as the most recent Texas gubernatorial election in which both major parties' nominees have since died.

Dorothy Ann Richards was an American politician who served as the 45th governor of Texas from 1991 to 1995. A Democrat, she first came to national attention as the Texas State Treasurer, when she gave the keynote address at the 1988 Democratic National Convention. Richards was the second female governor of Texas, and was frequently noted in the media for her outspoken feminism and her one-liners.
