1974 Dallas Cowboys season

The 1974 Dallas Cowboys season was their 15th in the league. The team failed to improve on their previous output of 10–4, winning only eight games. They failed to qualify for the playoffs for the first time in nine seasons and this marked the only season from 1966 to 1983 (18 seasons) that the Cowboys did not qualify.

The Cowboys began with a 1–4 start and although they went 7–2 afterwards, it was not enough to overcome the slow start.

The season featured one of the most memorable Thanksgiving Day games in Cowboys history. Trailing 16–3 in the second half (and having already lost quarterback Roger Staubach to injury), little used backup Clint Longley threw two touchdown passes to lead the team to a 17–16 victory over the Redskins at Texas Stadium.

1974 was the final season of hall of fame defensive tackle Bob Lilly.
