Men's Swimming EISL/Ivy League Champions
Princeton's EISL/Ivy League Championships
The Ivy League men's swimming championship was determined by round-robin standings until 1997, when the Eastern Intercollegiate Swimming League meet began determining the league champion. Navy no longer competes in the meet, so it is now considered the Ivy League Championships.
Princeton has won seven of the last eight Ivy League titles, as well as nine of the last eleven.
