2024 Swedish Open – Men's singles

Nuno Borges defeated Rafael Nadal in the final, 6–3, 6–2 to win the men's singles tennis title at the 2024 Swedish Open. It was his first ATP Tour title. Borges became the second Portuguese player in the Open Era to win a main tour singles title, after João Sousa. It was Nadal's first final since the 2022 French Open.

Andrey Rublev was the defending champion, but lost to Thiago Agustín Tirante in the second round.

The quarterfinal match between Nadal and Mariano Navone lasted four hours, becoming the third-longest best-of-three match since 1991. It was the second-longest best-of-three match of Nadal's career (after the 2009 Madrid Open semifinal against Novak Djokovic).
