1998 Wimbledon Championships – Boys' singles

Roger Federer defeated Irakli Labadze in the final, 6–4, 6–4 to win the boys' singles tennis title at the 1998 Wimbledon Championships. It was Federer's fourth juniors singles title. He would go on to win a record eight senior Wimbledon titles between 2003 and 2017.

Wesley Whitehouse was the reigning champion, but turned 18 years old during the season and, therefore, was ineligible to compete in juniors.
