1990 French Open – Men's singles

Andrés Gómez defeated Andre Agassi in the final, 6–3, 2–6, 6–4, 6–4 to win the men's singles tennis title at the 1990 French Open. It was his first and only major singles title. He became the first Ecuadorian, male or female, to win a major. Agassi would later write in his 2009 autobiography that he spent much of the final worried his wig would fall off.

Michael Chang was the defending champion, but he was defeated by Agassi in the quarterfinals. For the first time since the December 1977 Australian Open, none of the semifinalists had previously won a major title.

Until the 2002 Australian Open, this would be the last time that the top two seeds would lose in the first round of a major, with Stefan Edberg and Boris Becker losing to Sergi Bruguera and Goran Ivanišević respectively.
