One South Broad is an office building in Center City, Philadelphia, Pennsylvania, United States. The building was designed in the neo-classical style by John Torrey Windrim and was constructed from 1930 to 1932. The 28-storey building has a height of 472 ft (144 m) and a floor area of 465,000 ft (43,000 sq m).

One South Broad was originally named the Lincoln-Liberty Building. In 1952, the building was purchased by Philadelphia National Bank. By 1956, the building became home to the PNB after a modernisation project. It would house offices for the bank's successors, including Wells Fargo. From 1998 until 2000, the building was renovated at a cost of US$10,000,000.

On the top of One South Broad is a sign with the letters "PNB", which was installed in 1955. The building contains the 17-ton Founder's Bell. Floors 24 and 25 originally housed a penthouse apartment. The first seven floors housed the Wanamaker's Men's Store until 1952. The first floor housed a bank from 1952 until 1998 and was afterwards converted into retail and restaurant space.

The building originally had an ornate lower facade which was replaced in the 1950s with granite black slabs, which were, in turn, replaced by Italian granite in the lare 1990s renovation. The renovation also created a new entrance leading to a three-storey gallery lobby.
