1997–98 Princeton Tigers men's basketball team

Coaches vs. Cancer Classic Champion The 1997–98 Princeton Tigers men's basketball team represented Princeton University in intercollegiate college basketball during the 1997–98 NCAA Division I men's basketball season. The head coach was Bill Carmody and the team co-captains were Steve Goodrich and Mitch Henderson. Over the course of the season, the team achieved the highest winning percentage in the nation (93.1%, 27–2). It also established the current school record of 20 consecutive wins surpassing the 19-game streak achieved twice, including the prior season.

Using the Princeton offense, the team posted a 27–2 overall record and a 14–0 conference record. The team entered the tournament on a 19-game winning streak. In a March 12, 1998 NCAA Division I men's basketball tournament East Regional first round game at the Hartford Civic Center in Hartford, Connecticut, the fifth-seeded Tigers defeated 69–57. Then two days later in the second round the team lost to the Michigan State Spartans 63–56.

The team's season-opening 62–56 win against Texas in the Coaches vs. Cancer Classic on November 11, 1997, was the team's last win against a ranked opponent until the 2011–12 team defeated Harvard on February 11, 2012. During the season, the team entered the fourth Associated Press Top Twenty-five Poll (for the week of December 2) ranked twenty-fifth and climbed steadily each week until it ended the season ranked eighth.

The team was led by first team All-Ivy League selections Goodrich and Gabe Lewullis. With two first team selections and two second team selections (Brian Earl & Mitch Henderson), this was the fourth team (and third Princeton team) to have four first and second team selections.

The team won the tenth of twelve consecutive national statistical championships in scoring defense with a 51.4 points allowed average. The team also led the nation in assist-turnover ratio (1.63) and fewest turnovers per game (10.14). The assist-to-turnover ration was a national record that lasted until 2005. The team continues to be a contributor to the national record for combined single-game three-point field goal shooting percentage (72.4%, minimum 20 made) stemming from a February 20, 1998, contest in which they made 12 of 15 attempts, while made 9 of 14 attempts. Two-time defending Ivy League field goal percentage statistical champion Goodrich was unable to repeat a third time, but instead he won the three-point field goal shooting percentage title with a 51.4% average.
