Regent Square is a distinct neighborhood in the East End of Pittsburgh, Pennsylvania. According to the Regent Square Civic Association, it is "a neighborhood that includes portions of the municipalities of Pittsburgh, Edgewood, Swissvale and Wilkinsburg." It is also the name of one of the 65 neighborhoods within the City of Pittsburgh's limits, which leads to some confusion among residents. The neighborhood is split between ZIP codes 15218 and 15221; the part of the neighborhood within the City of Pittsburgh is represented on the City Council by the council seat for District 5. Despite its division among four municipal governments and three school districts, Regent Square's identity bolstered by an active community association. Geography also helps to give Regent Square a distinct identity: the neighborhood is a roughly rectangular plateau bounded on three sides by the steep valleys of Fern Hollow Creek to the west and Nine Mile Run to the south and east.
