The 1966 New York Mets season was the fifth regular season for the Mets. They went 66–95 and finished ninth in the National League. They were managed by Wes Westrum. They played home games at Shea Stadium. 1966 marked the first season in which the Mets avoided a last place finish, as well as the first time they did not lose at least 100 games. It was also the first time their record was above .500 at any point of the season, as they stood 2-1 after taking two of three games in the opening series with the Atlanta Braves.
