Alphonso Boyle Davies (born November 2, 2000) is a professional soccer player who plays as a left-back for Bundesliga club Bayern Munich and captains the Canada national team. Regarded as one of the best full-backs in the world, Davies has earned the nickname "the Roadrunner" for his pace, dribbling ability, and creativity.

Davies was the first player born in the 2000s to play in a Major League Soccer match. He joined Bayern in January 2019 from MLS side Vancouver Whitecaps FC on a contract lasting until 2023 for a then-record MLS transfer fee, and in February 2025 signed a new contract with Bayern Munich until June 2030. Davies was named the Bundesliga Rookie of the Season for 2019–20. In that season he also was part of the team winning the continental treble after Bayern won the Bundesliga, the UEFA Champions League and the DFB-Pokal. His performances led him to be a finalist of 2020 Golden Boy award.

Born a Liberian refugee in Ghana, Davies and his family relocated to Canada when he was five years old. Davies obtained Canadian citizenship in June 2017; he was until then a Liberian national. Later that month, he became the youngest player to appear for the Canada national team. By scoring two goals in a 2017 CONCACAF Gold Cup match against French Guiana, he became the youngest player to score for the team, the youngest to score at the CONCACAF Gold Cup, and first player born in the 2000s to score at a top level international tournament. He would go on to be named CONCACAF Men's Player of the Year in 2021 and 2022. Davies was called up to play in the 2022 FIFA World Cup, where he scored Canada's first ever goal at a men's World Cup. He is widely considered both the best player on and the face of the Canada national team.

Davies is the first soccer player, and first Canadian, to become an ambassador for the United Nations refugee agency, UNHCR.

Davies was born to Liberian parents in Buduburam, a refugee camp in Ghana, the fourth youngest of six siblings. His father, Debeah Davies, and his mother, Victoria Davies, originally lived in Monrovia, the capital of Liberia. They fled during the Second Liberian Civil War, which displaced more than 450,000 Liberians. In 2005, the family emigrated to Canada, eventually settling in Edmonton. After moving to Edmonton, Davies attended Mother Teresa Elementary School. At the age of 14, Davies relocated alone to Vancouver to join the Whitecaps FC Residency program. As part of the program, he attended Burnaby Central Secondary School. On June 6, 2017, he received Canadian citizenship; until then he had been a Liberian national.

Davies attended St Nicholas Catholic Junior High in the Edmonton Catholic School District. His school soccer teammate Onesphore Hamis recalled, "Soccer was the thing he wanted to get into, but language was a problem." His classmate and fellow Liberian immigrant Chernoh Fahnbulleh recalled of Davies, "He spoke English but it was, like, broken English".

As a child in Edmonton, Davies first played organized soccer with Free Footie, an after-school soccer league for inner-city elementary school students who cannot afford registration fees and equipment, or who lack transportation to games.

After playing for Edmonton Internationals, and Edmonton Strikers, Davies joined the Whitecaps FC Residency in 2015 at the age of 14.
