The 1948 Oregon State Beavers football team represented Oregon State College in the Pacific Coast Conference (PCC) during the 1948 college football season. In their fourteenth season under head coach Lon Stiner, the Beavers compiled a 5–4–3 record (2–3–2 in PCC, sixth), defeated Hawaii in the Pineapple Bowl on New Year's Day, and outscored their opponents 249 to 236.[1]
Oregon State was ranked at No. 54 in the final Litkenhous Difference by Score System ratings for 1948.[2]
The team played its home games on campus at Bell Field in Corvallis and at Multnomah Stadium in Portland.
The following spring at age 45, Stiner resigned as head coach on March 7.[3] [4] He said at the time, "A football coach must have full support in his job. I have had excellent support in the past but when the full support no longer exists, a change is for the best for all parties concerned."[5] With 16 years of service, he was the dean of the PCC football coaches.[5] He compiled a record of 74–49–17 (49–42–13 in PCC) as head coach.
