1883 Philadelphia Quakers season

The 1883 season was the first in the history of the Philadelphia Phillies. The team was founded earlier in the year as a replacement for the Worcester franchise. It was the first year Philadelphia was represented in the National League since the original Athletics were disbanded in 1876 after refusing to finish the season. The American Association's Philadelphia Athletics had been founded a year earlier.

The team opened the year managed by Bob Ferguson; however, he was fired as manager after a disappointing 4–13 start and replaced by Blondie Purcell. The team finished the season 17–81, worst in the National League.

Preseason
The Phillies played their first game ever on April 2, 1883, and defeated the amateur Manayunk Ashlands in an exhibition game by the score of 11–0 at Recreation Park.
