1999 Colgate Red Raiders football team

The 1999 Colgate Red Raiders football team was an American football team that represented Colgate University during the 1999 NCAA Division I-AA football season. Colgate was the Patriot League co-champion, but lost in the first round of the national Division I-AA playoffs.

In its fourth season under head coach Dick Biddle, the team compiled a 10–2 record. Tom McCarroll and Ryan Vena were the team captains.

The Red Raiders outscored opponents 430 to 253. Colgate's 5–1 record earned a tie for the Patriot League championship.

Unranked in the preseason Division I-AA national poll, the Red Raiders briefly appeared at No. 24 early in the season, then returned to the top 25 in mid-November. Colgate ended the year ranked No. 18 and qualified for the Division I-AA playoffs by winning its conference, even though it was the lower-ranked of the two Patriot League co-champions; Lehigh also qualified, however, with an at-large berth. Both Patriot League playoff teams lost in the first round.

Colgate played its home games at Andy Kerr Stadium in Hamilton, New York.
