2023 Wimbledon Championships - Boys' 14&U singles

In only the second time this discipline was held, South Korea's Se Hyuk Cho was the defending champion, but he was no longer eligible to participate in the under 14 tournament this year. He didn't return to play in the boys event either. GB's Mark Ceban won the title by defeating Slovenia's Svit Suljic in straight sets.

Format
The first phase of the tournament sees four round-robin groups compete. The winners of each group will advance to the semi-finals. The rest will compete in a consolation play-off tournament.

Group D
''Standings are determined by: 1. number of wins; 2. number of matches played; 3. in two-players-ties, head-to-head records; 4. in three-players-ties, percentage of sets won, then percentage of games won.''
