Regent Square is a neighborhood in the East End of Pittsburgh, Pennsylvania, United States.

According to its civic association, it "includes portions of the municipalities of Pittsburgh, Edgewood, Swissvale and Wilkinsburg".

[2] It is also the name of one of the 90 neighborhoods within the City of Pittsburgh's limits, which leads to some confusion among residents.

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.

Regent Square is bordered by the Pittsburgh neighborhoods of Point Breeze to the north, Squirrel Hill South to the west, and Swisshelm Park to the south; and by the boroughs of Swissvale to the southeast, Edgewood to the east, and Wilkinsburg to the northeast.
