1905 Iowa State Cyclones football team

The 1905 Iowa State Cyclones football team represented Iowa State College of Agricultural and Mechanic Arts (later renamed Iowa State University) as an independent during the 1905 college football season. In their fourth season under head coach A. W. Ristine, the Cyclones compiled a 6–3 record, and outscored all opponents by a combined total of 203 to 93. Preston Daniels was the team captain. Don Stoufer was the team captain.

Between 1892 and 1913, the football team played on a field that later became the site of the university's Parks Library. The field was known as State Field; when the new field opened in 1914, it became known as "New State Field".
