The 1966 season was the Chicago Bears' 47th in the National Football League. The team failed to improve on their 9–5 record from 1965 and finished with a 5–7–2 record under head coach George Halas, earning them a fifth-place finish in the NFL Western Conference. This was the franchise's second losing season in the past three.
