The 2018 Philadelphia Phillies season was the 136th season in the history of the franchise, its 15th season at Citizens Bank Park, and the 1st season with manager Gabe Kapler. They improved from their 66–96 season in 2017 by posting an 80–82 record, but missed the postseason for the seventh consecutive season. Kapler had the second-most wins among Phillies managers historically after 100 games (56), and under Kapler, the 2018 team improved its end-of-season won-lost record by 14 games.
