Anthony Stewart is a Canadian former professional ice hockey player, having played in the NHL, AHL, and KHL. He was born in Quebec, and his family moved to Toronto while he was a child. Stewart played minor hockey in Toronto, winning three all-Ontario championships. After his minor hockey career, he was selected by the Kingston Frontenacs in the first round of the Ontario Hockey League (OHL) draft. After two seasons with Kingston, he was drafted by the Florida Panthers in the first round of the 2003 NHL Entry Draft, at 25th overall. He spent four years in the Panthers' system, dividing his time between the NHL and the American Hockey League (AHL), after which he joined the Atlanta Thrashers for two years. When the Thrashers moved to Winnipeg to become the new Winnipeg Jets, they did not offer him a new contract, and he signed with the Carolina Hurricanes as a free agent. After one season in Carolina he was traded to the Kings, but spent most of the season in the minor leagues. He signed a professional tryout contract with the San Jose Sharks to begin the 2013–14 NHL season, but was not offered a contract. He subsequently signed with Avtomobilist Yekaterinburg in the KHL. His younger brother Chris also played in the NHL, and retired after the 2019–2020 season playing for Philadelphia Flyers.
