Canadian Mounties vs Atomic Invaders (1953) is a Republic Movie serial starring Bill Henry and both produced and directed by Franklin Adreon.

A foreign power, which is represented by their agent Marlof, attempts to set up secret missile bases in Canada to target the United States for their planned summer invasion.

Though filmed entirely in the United States, early chapters in Canadian Mounties vs. Atomic Invaders are set in a snowy region of northern Canada referred to as Taniak and rely heavily on the use of footage from earlier Republic productions including the 1938 feature Call of the Yukon and serials King of the Royal Mounted and King of the Mounties.

[1] Canadian Mounties vs. Atomic Invaders was one of twenty-six Republic serials re-released as a 100-minute "Century 66" feature film on television in 1966, titled Missile Base at Taniak.
