Elton P. "Ice Box" Chamberlain (November 5, 1867 – September 22, 1929) was an American professional baseball player. He played in Major League Baseball as a right-handed pitcher from 1886 to 1896. In several seasons, Chamberlain finished in his league's top ten in a number of pitching categories, including wins, earned run average, strikeouts, and shutouts. During one of his best seasons, the 1888 St. Louis Browns won the American Association pennant with a 92–43 record. Although a righthanded pitcher, Chamberlain pitched the last two innings of an 1888 game with his left hand.
