The 1964 ECAC Hockey Men's Ice Hockey Tournament was the 3rd tournament in league history. It was played between March 6 and March 14, 1964. Quarterfinal games were played at home team campus sites, while the 'final four' games were played at the Boston Arena in Boston, Massachusetts. By reaching the championship game Providence was invited to participate in the 1964 NCAA Division I Men's Ice Hockey Tournament. St. Lawrence, however, was passed over with Rensselaer chosen instead as the second eastern representative.
