The 1977 NCAA Division II Lacrosse Championship was the fourth annual single-elimination tournament to determine the national champions of NCAA Division II and Division III men's college lacrosse in the United States.
A separate Division III men's championship would not be introduced until 1980.
This year's final was played at Boswell Field at the Hobart College in Geneva, New York.[1]
Defending champions Hobart defeated Washington College, 23−13, to win their second national title. This marked four consecutive championship game appearances for Hobart.
The undefeated Statesmen (15–0) were coached by Jerry Schmidt.
