1890 Princeton Tigers football team

The 1890 Princeton Tigers football team represented Princeton University in the 1890 college football season. The team finished with a 12–1–1 record. The Tigers recorded nine shutouts and outscored opponents by a combined total of 494 to 63. The team's sole loss was by a 32–0 score against Yale.

Three Princeton players (fullback Sheppard Homans, Jr., end Ralph Warren, and guard Jesse Riggs) were consensus first-team honorees on the 1890 College Football All-America Team. In 1952, Grantland Rice paid tribute to Homans as the embodiment of the rough and tumble days of iron man football. Rice wrote: "Just as Ty Cobb represents the ball game of many years ago, this man represented the football that used to be."
