James "the Perch" Carl Winkler (July 21, 1927 – February 14, 2001) was a defensive lineman who played three seasons in the National Football League (NFL).

In his autobiography, NFL Hall of Famer Art Donovan described Winkler as "the craziest football player I have ever met," and he shared this anecdote, among others: "When he joined us, we immediately dubbed him "the Perch", because he had a face like a fish.

Donovan went on to describe how Winkler once refused to play in a game against the Rams because they were his former teammates.

[1] An article in the July 25, 1954 issue of The Baltimore Sun acknowledged that Winkler experienced personal problems in his lone season with the Colts but stated that Winkler asked Coach Weeb Ewbank for his release due to a shoulder injury.
