According to sources familiar with Richards, the actor was raised Catholic. A biography of him on the Wikipedia web site lists no religion, but does say Richards is very involved in the Masons.
Unnamed "sources familiar?"
His being confused as a Jew because of the character he played can result in some strange consequences and excuses.
I am willing to bet he is not Jewish, "Unnamed sources" and all.

KRAZY KRAMER WENT OFF ON A JEW RANT, TOO
By HASANI GITTENS and DAVID K. LI
November 23, 2006 -- Michael Richards spewed anti-Semitic rants during a show earlier this year, witnesses said yesterday, as sickening new details of the comic's recent racist tirade came to light.
Two customers at a Richards performance last spring told the celebrity-news Web site tmz.com that the "Seinfeld" comic - who is Jewish - lashed out at Jews after he was heckled onstage.
"Michael Richards said, 'You're a f- - -ing Jew.' Your people are the cause of Jesus dying," said witness Carol Oschin, recalling an April 22 act at The Improv in Los Angeles.
Richards soon stormed off stage, leaving audience members as confused as they were offended, said Oschin and another witness, J.P. Fillet.
"We didn't know if this was part of the act . . . He was getting very [verbally] violent, very agitated," Oschin said.
Richards, in frantic damage-control mode, hired New York p.r. maestro Howard Rubenstein yesterday. And the famed mouthpiece confirmed his client used anti-Semitic words that night in California.
"He is Jewish and he said, 'I'm absolutely not anti-Semitic,' " Rubenstein said. "He acknowledged that he said those things. He said that he was role-playing and playing a character. He said, 'There is no way I'm anti-Jewish.' "
