The Argonaut Rowing Club is an amateur rowing club in Toronto, Ontario, Canada. The club was founded in 1872.

In the past, the club also fielded teams in ice Hockey and football, and the football team continues today as the Toronto Argonauts of the Canadian Football League / CFL.

The club fielded ice Hockey teams in the Ontario Hockey Association / OHA on and off from 1904 to 1923. The Argonauts operated senior ice Hockey, intermediate ice Hockey and junior ice Hockey teams during their time in the OHA. The junior team won the J. Ross Robertson Cup as OHA champions in the 1911–12 season and the 1919–20 season. The junior team also won the national championship at the 1920 Memorial Cup, participating under the name Toronto Canoe Club Paddlers.

The ice Hockey team is credited by Frank Selke as the originators of the modern defence pairing. Until 1906, defencemen in ice Hockey were known as the point and cover point. The two points lined up one behind the other at face offs. The Argonaut team moved the players to left and right in the positions used today. The setup is considered to be originated from the style of plays of the Argonauts. The team ran set plays reminiscent of football, and moved the players to fit the set plays. The Argonauts were very successful in the first decade of the 1900s and the style caught on in the OHA.
