Christos Tzolis (born 30 January 2002) is a Greek professional footballer who plays as a left winger for Arsenal and the Greece national team. After rising through the ranks at PAOK, he moved to Norwich City in 2021, but his career truly flourished on loan at Fortuna Düsseldorf in the 2023–24 season, where he finished as the 2. Bundesliga's joint-top scorer with 22 goals.

In July 2024, he joined Club Brugge for €6 million, where he was named Belgian Pro League Player of the Season after scoring 22 goals and providing 29 assists while leading the club to the league title in 2025–26. His performances earned him a £34 million move to Arsenal in July 2026, where he made a stunning debut in the FA Community Shield by providing two assists—a feat not achieved in the competition since David Beckham in 1996. On the international stage, Tzolis made his senior debut for Greece in October 2020, becoming the seventh-youngest player in the nation's history, and scored his first international goal the following month.
