George Andrew McNamara (August 26, 1886 – March 10, 1952) was a Canadian professional ice hockey player.

George and his brother, Howard, also briefly a member of the Soo Marlboros, were known as the "Dynamite Twins" because of their bone-crunching body checks.

His professional hockey career was interrupted in 1916 when he enlisted in the Canadian Army during the First World War, along with brother Harold.

He was a member of the 228th Battalion team that played in the National Hockey Association before being ordered overseas on February 10, 1917.

[1] McNamara served in this capacity for the duration of the war, and was Mentioned in Dispatches and promoted to major before being discharged and returning to Canada in March 1919.
