1966 Philadelphia Phillies season

In 1966, the Philadelphia Phillies had a winning record of 87–75. Over the course of the campaign, they held winning records against two of their biggest regional rivals, the Pittsburgh Pirates (10–8) and New York Mets (11–7), respectively. Philadelphia had the fourth-highest winning percentage in the National League (NL) that year. The Phillies were owned by R. R. M. "Bob" Carpenter, Jr., with the Phillies playing home games in Connie Mack Stadium, as they had since 1938.

In the off-season, the Phillies purchased, sold, and traded several players. Among those purchased by other teams was Mike Marshall, sold to the Detroit Tigers on April 11, 1966. Throughout its history, players could be added to the team in several ways, including advancement to the parent club through the farm system. The primary farm teams were the Triple-A San Diego Padres and Double-A Macon Peaches. Phillies farm system players who made their MLB debut with the 1966 squad are pitchers John Morris and Joe Verbanic, and infielder Gary Sutherland.
