Context: The 2003–04 Princeton Tigers men's basketball team represented Princeton University in intercollegiate college basketball during the 2003–04 NCAA Division I men's basketball season.  The head coach was John Thompson III and the team captains were Ed Persia and Judson Wallace.  The team played its home games in the Jadwin Gymnasium on the University campus in Princeton, New Jersey, and was the champion of the Ivy League, which earned them an invitation to the 65-team 2004 NCAA Men's Division I Basketball Tournament where they were seeded fourteenth in the Atlanta Region.  Following the season Thompson departed to coach Georgetown where his father John Thompson, Jr. had coached for decades.  He was replaced by Joe Scott.  Both Scott and the younger Thompson are former Princeton Tigers basketball captains. The Penn–Princeton basketball rivalry is an American college basketball rivalry between the Penn Quakers men's basketball team of the University of Pennsylvania and Princeton Tigers men's basketball team of Princeton University.  Having been contested every year since 1903, it is the third oldest consecutively played rivalry in National Collegiate Athletic Association Division I history.  Unlike many notable college basketball rivalries, such as Carolina–Duke, which involves teams that often both get invited to the same NCAA tournaments, Notre Dame–UCLA, which involves geographically remote teams, Illinois–Missouri, which involves non-conference rivals, or Alabama–Auburn, which takes a back seat to the football rivalry, this is a rivalry of geographically close, conference rivals, who compete for a single NCAA invitation and consider the basketball rivalry more important than other sports rivalries between the schools.  A head-to-head contest has been the final regularly scheduled game of the Princeton season every year since 1995.  Between 1963 and 2007, Princeton or Penn won or shared the Ivy League conference championship every season except 1986 and 1988.  The other seasons in which neither team won or shared the Ivy League title are 1957, 1958, 1962, 2008–10, and 2012-2016.
