2005 NCAA Division I men's lacrosse tournament

The 2005 NCAA Division I lacrosse tournament was the 35th annual tournament hosted by the National Collegiate Athletic Association to determine the team champion of men's college lacrosse among its Division I programs, held at the end of the 2005 NCAA Division I men's lacrosse season.

Johns Hopkins won the championship with a 9–8 win over Duke. The Blue Jays, led by senior Kyle Harrison and sophomore goalie Jesse Schwartzman, won their eighth NCAA championship and first since 1987. All the while, Johns Hopkins allowed just one goal the entire second half of the game. Schwartzman was named the tournament's outstanding player.

In an exciting national semi-final game, Hopkins won against Virginia in overtime on a goal by defensive short stick midfielder Benson Erwin. Virginia seemingly had the game locked up in regulation after scoring the go ahead goal with 12.9 seconds remaining. But Hopkins won the ensuing face off and raced down the field tying the game with 1.5 seconds to go, setting up Erwin's overtime heroics.

The championship game was played at Lincoln Financial Field in Philadelphia, Pennsylvania, with an audience of 44,920 fans, the 4th highest total for an NCAA lacrosse final.
