The 1965–66 Boston Celtics season was their 20th in the National Basketball Association (NBA).

On October 29, 1965, Sam Jones set a Celtics single-game scoring record with 51, against the Detroit Pistons. His record would last until Larry Bird's 53 in 1983. The Celtics won their 8th title in a row, which still stands as a record for the most titles in a row. The Celtics defeated the Lakers 4 games to 3.

This also marked the final season Red Auerbach coached the Celtics, though his duties with the team only expanded as general manager in the following seasons; he would remain involved with the team in some form until his death 40 years later.
