Super-Patriot is a name used by three fictional characters in the universe of Marvel Comics. The first was an enemy of Nick Fury and S.H.I.E.L.D. The second was John Walker, who used the name Super-Patriot as a rival to Captain America. When Steve Rogers gave up the role of Captain America, Walker was tapped by the Commission on Superhuman Activities to replace Rogers; Walker later adopted the moniker U.S. Agent after Rogers' return. The third person to use the alias was Mike Farrell, a former neighbor of Steve Rogers, who became Super-Patriot and allied himself with Dead Ringer, a mutant villain with the power to mimic.
