2017 Aegon International Eastbourne – Men's singles

Feliciano López was the champion in 2014, when the men's event was last held, but withdrew before the tournament began.

Novak Djokovic won the title, defeating Gaël Monfils in the final, 6–3, 6–4. This tournament marked the first time since 2010 that Djokovic played a grass-court tournament before Wimbledon. It was also the only tournament that Djokovic won without his coach being Marián Vajda until the duo split in 2022.
