Riley Cote is a Canadian former professional ice hockey left winger and is currently an assistant coach with the Adirondack Phantoms of the American Hockey League (AHL). He played four National Hockey League (NHL) seasons with the Philadelphia Flyers and was mainly known as an enforcer.

Undrafted after completing juniors, Cote was a walk on to the Toronto Maple Leafs training camp in fall 2002. He impressed the Leafs staff, signed a one-year contract, and was assigned to the Leafs Central Hockey League affiliate, the Memphis RiverKings. While called up to the St. John’s Maple Leafs, Toronto’s American Hockey League affiliate, a few times during the 2002–03 season, he spent most of his rookie year with the RiverKings and was with them when they won the CHL championship that season.

Not re-signed by the Leafs, Cote was signed to a two-way contract by the Syracuse Crunch of the AHL and entered the training camp for their NHL affiliate, theColumbus Blue Jackets, in fall 2003. Columbus released him and he returned to the Crunch. An eye injury caused during a pre-season scrimmage resulted in Cote being assigned to the Crunch’s ECHL affiliate, the Dayton Bombers, for much of the 2003–04 season. Cote was recruited back to the RiverKings for the 2004–05 season but was offered a try-out contract by the AHL’s Philadelphia Phantoms just before the season began. The Phantoms extended his contract 3 times throughout the season where he eventually spent the entire season with Philadelphia, accumulating a team-leading 280 penalty minutes in the process, and helped the Phantoms win the Calder Cup as league champions. Shortly after the season ended, the Phantoms signed him to a one-year contract.

After participating in the Philadelphia Flyers training camps in the fall of 2005 and 2006, Cote was signed to a two-way contract by the Flyers in 2006–07. Early in the season, he was assigned to the Phantoms and shortly after suffered an ankle injury that kept him from playing for two months. Late in the season, Cote played in his first 8 NHL games with the Flyers, making his NHL debut on March 24, 2007 against the New York Islanders. Cote was recognized for his contributions to the community when the Phantoms named him as the team’s 2006–07 Man of the Year. Cote was re-signed by the Flyers to a one-year contract for the 2007–08 season and made the team out of training camp.
