* – Selected as Rose Bowl representative
Oregon State won the Civil War game over Oregon, but no-repeat rule was in effect
The 1957 Oregon State Beavers football team represented Oregon State College in the 1957 NCAA college football season. The Beavers ended this season with a record of 8–2. The team captains were Ted Searle. The Beavers scored 203 points and allowed 129 points. Led by head coach Tommy Prothro, Oregon State won their second consecutive Pacific Coast Conference championship, the only time the Beavers have won consecutive conference championships. However, Oregon State became the last Pacific Coast Conference team to fall victim to the conference's no-repeat rule and was unable to represent the conference in the Rose Bowl. Rival Oregon, which had lost to the Beavers, went to the Rose Bowl instead.
