The Union League of Philadelphia is a private club founded in 1862 by the Old Philadelphians as a patriotic society to support the policies of Abraham Lincoln.

Union League clubs, which are legally separate but share similar histories and maintain reciprocal links with one another, are also located in Manhattan, Chicago, Brooklyn, and New Haven, Connecticut.

A politically conservative club, it has faced criticism for awarding figures such as Florida Governor Ron DeSantis with a gold medal.
