The 1965 NFL playoffs determined the champion of the National Football League in professional American football for its 1965 season. Although a single championship game between conference winners was the current format for the league, a tie in the Western Conference standings between the Green Bay Packers and Baltimore Colts necessitated a rare tiebreaker playoff, the first in the league in seven years and the first in the Western Conference since 1957. A coin flip decided the home team. The teams had played twice during the regular season and Green Bay had won both: 20–17 in Milwaukee on September 26, and 42–27 in Baltimore on December 12.
