is a South Korean professional footballer who plays as a forward for and captains both Premier League club Tottenham Hotspur and the South Korea national team. Known for his speed, finishing, two-footedness, and ability to link play, he is the top Asian goalscorer in both Premier League and UEFA Champions League history and is widely regarded as the greatest Asian player of all time.

Born in Chuncheon, South Korea, Son relocated to Germany to join Hamburger SV at 16, making his debut in the Bundesliga in 2010. In 2013, he moved to Bayer Leverkusen for a club record €10 million before signing for Spurs two years later. While at Spurs, Son soon established himself as one of the best forwards in the world. He contributed to the club reaching the Champions League final in 2018–19 and the EFL Cup final in 2020-21. In 2019-20, Son scored a solo effort in the league that earned him the FIFA Puskás Award. In the 2021–22 season, he jointly won the Premier League Golden Boot award with 23 goals, becoming the first Asian player to win it. In April 2023, he became the first Asian player to score 100 Premier League goals. Appointed club captain later in 2023, he led Spurs to the UEFA Europa League title in 2025, his first major honour, whilst also ending a 17-year trophy drought for the club.

A full international since 2010, Son has represented South Korea at the 2014, 2018, and 2022 FIFA World Cups and is his country's joint top scorer at World Cups, tied with Park Ji-sung and Ahn Jung-hwan on three goals. Son has also represented South Korea at the 2018 Asian Games, where the team won gold, and the 2011, 2015, 2019, and 2023 editions of the AFC Asian Cup; Korea was the runner-up in 2015.

Outside of football, Son is viewed as a symbol of national pride in South Korea for his achievements, and has been listed in Forbes Korea Power Celebrity 40 since 2019, where he ranked second in 2024. In June 2022, Son received the Cheongnyong Medal, the highest order of merit for achievement in sports given to a South Korean citizen, for his achievements in football. Son has been credited for having raised the profile of Spurs among South Koreans, with the club's marketing and social media strategy catering extensively to Korean supporters.
