The Reading Fightin Phils (also called the Reading Fightins) are a minor league baseball team based in Reading, Pennsylvania, playing in the Northeast Division of the Double-A Northeast. The team plays their home games at FirstEnergy Stadium. The Reading Fightin Phils were founded in 1967 as the Reading Phillies (commonly referred to as the R-Phils and sometimes Reading Phils) and they are the Double-A affiliate of the Philadelphia Phillies since 1967. This affiliation is currently tied for the longest affiliation in Minor League Baseball. The Phillies bought the team outright in 2008. Many fans still refer to the team as the Reading Phillies or R-Phils. They were members of the Eastern League from 1967 to 2020.

The franchise has always been based in Reading and maintained its original name "Reading Phillies" from its establishment in 1967 through 2012. The Reading Fightin Phils are the oldest team in the Eastern League to play in their original and current city with the most seasons under their original name (Reading Phillies).
