The 2004 NCAA Division I Men's Swimming and Diving Championships took place March 25–27, 2004 in the Nassau County Aquatic Center, East Meadow, New York. 21 champions were declared.
Along with 2000, this year's meet was held short course meters (25 meters), rather than the NCAA's traditional short-course yards format (25 yards). This allowed for World Records to be set at the meet.
