1989 French Open – Men's singles

Michael Chang defeated Stefan Edberg in the final, 6–1, 3–6, 4–6, 6–4, 6–2 to win the men's singles tennis title at the 1989 French Open. It was his first major title. Chang remains the youngest-ever men's singles major champion, winning the final at the age of 17 years, 3 months, 23 days, and the first player (male or female) of Asian descent to win a major. En route to the title, he defeated the world No. 1 and three-time champion Ivan Lendl, which is remembered as one of the most significant matches in French Open history.

Mats Wilander was the defending champion, but he lost in the quarterfinals to Andrei Chesnokov.
