1909 Colorado Silver and Gold football team

The 1909 Colorado Silver and Gold football team was an American football team that represented the University of Colorado as a member of the Colorado Faculty Athletic Conference (CFAC) during the 1909 college football season. In its ninth season under head coach Fred Folsom, the team compiled a perfect 6–0 record (3–0 against CFAC members), won the conference championship, was unscored upon for the season, and outscored opponents by a total of 141 to 0.

Colorado sustained a 21-game win streak that began on November 26, 1908, and ended on October 12, 1912. It remains the longest such streak in program history.

The 1909 season was the first for the CFAC; it became the Rocky Mountain Conference for the following season.
