Gallitzin is a borough in Cambria County, Pennsylvania, United States. It is bordered by Gallitzin Township and Tunnelhill, all of which sit astride the Eastern continental divide. Tunnel Hill and Gallitzin both are pierced by railroad tunnels shortening the necessary ascent for rails crossing the Allegheny Front onto the Allegheny Plateau which encompasses the towns' terrains. Topping the gaps of the Allegheny, the area is one of only five major breaks in the Appalachians allowing east–west transportation corridors before the advent of 20th century technologies.
