John Alan Grefe (born September 6, 1947 in Hoboken, New Jersey, died December 22, 2013) was an American International Master of chess. His best result was a tie for first with Lubomir Kavalek in the 1973 U.S. Championship. FIDE awarded him the title of International Master in 1975. Grefe and Stuart Rachels are the only players since 1948 to win or share the U.S. Championship without already having, or later achieving, the title of International Grandmaster. Grefe, at the time he shared the championship, lived in Berkeley, California, and was a follower of the Guru Maharaj Ji. For that reason and also because of his hippyish appearance, Grefe was affectionately known as "Gandalf" amongst chess friends.
Before his success in the U.S. Championship, Grefe had been fairly successful in Swiss system tournaments in the United States. He tied for eighth in the 1969 and 1971 U.S. Open, tied for first in the 1971 National Open, finished sixth at Lone Pine 1971, tied for fourth through sixth at Lone Pine 1973, and finished sixth in the 1973 U.S. Open.
