The 1990 LPGA Championship was the 36th LPGA Championship, played July 26–29 at Bethesda Country Club in Bethesda, Maryland, a suburb northwest of Washington, D.C. Five strokes back, Beth Daniel shot a final round 66 (−5) for 280 (−4) to win her sole major title, a stroke ahead of runner-up Rosie Jones, the third round leader. This was the first of four consecutive LPGA Championships at Bethesda Country Club. The purse (and winner's share) were doubled this year, at $1 million and $150,000, respectively.
