The 1965 WCHA Men's Ice Hockey Tournament was the 6th conference playoff in league history. The tournament was played between March 5 and March 13, 1965. All games were played at home team campus sites. By reaching the title game both Michigan Tech and North Dakota were invited to participate in the 1965 NCAA University Division Men's Ice Hockey Tournament.
This was the final season that the WCHA named a single tournament champion until 1977.
The top four teams in the WCHA, based upon the conference regular season standings, were eligible for the tournament and were seeded No. 1 through No. 4. In the first round the first and fourth seeds and the second and third seeds were matched in two-game series where the school that scored the higher number of goals was declared the winner. The winners advanced to the title game which was to be played at the higher remaining seed's home venue.
