The 1965Oakland Raiders season was the team's sixth in both Oakland and the American Football League. The campaign saw the team attempt to improve upon the prior year's disappointing 5–7–2 record. The Raiders would ultimately finish with a record of 8–5–1. While the effort was a definite improvement over the prior year's result, it was not enough to win the division and secure a postseason berth. The season would be Al Davis' last as head coach, as he would be named Commissioner of the AFL in April 1966. He would be replaced by John Rauch in 1966.
The 1965 season was the first of sixteen consecutive winning seasons for the Raiders. It is also notable for the debut of Hall of Fame wide receiver Fred Biletnikoff. Biletnikoff would be the first of several legendary Raiders drafted in the late-1960s and early 1970s. He would be an integral part of the team's 1967 and 1976 Super Bowl runs.
