The 1966 Dallas Cowboys season was the seventh for the franchise in the National Football League. The Cowboys, who had never previously finished with a winning record in their history, would improve dramatically. Dallas finished 10–3–1 and won the Eastern Conference title, their first of six consecutive division titles. They hosted the NFL Championship Game at the Cotton Bowl, where they lost to the defending NFL champion Green Bay Packers, thus missing out on the chance to play in the first Super Bowl which the Packers went on to win two weeks later.
