Trainer is a borough in Delaware County, Pennsylvania, sitting on the northwest bank of the Delaware River between Marcus Hook and the city of Chester.

Trainer is named after David Trainer Sr., the wealthy owner of the Linwood Mills textile works.

Trainer was originally part of Lower Chichester Township and was incorporated as a borough in 1919.

As of the 2020 census, Trainer had a population of 1,976, and the 2000 census counted 712 households in the borough.

Trainer's population peaked in the mid-20th century era of Delaware River industry, reaching 2,358 residents in 1960.

The Trainer Refinery on the Delaware River waterfront is owned by Delta Air Lines (through its Monroe Energy subsidiary), which bought the refinery from Phillips 66 in 2012 for $180 million — an unusual case of an airline owning an oil refinery to supply its own jet fuel.

Trainer's riverfront is heavily industrialized and forms an extension of the Port of Chester, with the Stoney Creek rail yard in the borough.

Stoney Creek flows through Trainer and empties into the Delaware River at the borough's waterfront.

About 23% of Trainer's total area of 1.37 square miles is water, thanks to its Delaware River frontage.

Trainer is part of the Chichester School District, and its children typically attend Marcus Hook Elementary School, Chichester Middle School, and Chichester High School; the borough's own Trainer Elementary School closed in 1984.
