Asa Hoffmann (born 1943) is a FIDE Master in chess from the United States of America. He is known as "the sparring partner of champions". His peak FIDE rating is 2313. He was portrayed in the movie Searching for Bobby Fischer by actor Austin Pendleton, though Hoffmann does not like the eccentric way his character was played.
He was a New York City junior champion and was vice president of the Manhattan Chess Club.
Specialising in blitz chess, he has been described by Yasser Seirawan as "a near legendary figure in the New York City chess world" and a collection of his games entitled The Chess Gladiator (Intl Chess Enterprises, 1996) includes a blitz win against Bobby Fischer.
He is interviewed in the documentary Bobby Fischer Against the World along with Anthony Saidy, Larry Evans, Sam Sloan and Susan Polgar.
