The 1965 Cleveland Browns season was the team's 16th season with the National Football League. With an NFL-best 11–3 mark, the 1965 team finished just a shade better than the year before (10–3–1) and, just as they had in 1964, the Browns returned to the NFL Championship Game; however, this time, they lost 23–12 to the Green Bay Packers in the last title contest held before the advent of the Super Bowl. It would be the first of three straight NFL crowns for the Packers, who went on to win the first two Super Bowls as well.
