The Saint Anthony Hall Trinity College chapter house is an historic fraternity building located at 340 Summit Street in Hartford, Connecticut.

The building was completed at a cost of $68,00—$40,000 of which was donated by Robert Habersham Coleman, an 1877 Trinity graduate and Delta Psi fraternity member, who become, albeit briefly, the wealthiest man in the United States.

Saint Anthony Hall is located on Gallows Hill, topographically the highest elevation Hartford, just north of the Trinity College campus, on the corner of Summit Avenue and Allen Place.

It is a two–story High Victorian Gothic style building finished with a façade made of quarried New Hampshire granite laid in random courses.
