Fitler Square is a 0.5 acre (0.20 ha) public park in Philadelphia, Pennsylvania, United States and a surrounding neighborhood of the same name.

The neighborhood encompasses much of southwest Center City west of Rittenhouse Square and east of the Schuylkill River.

The neighborhood is mostly residential, composed of single-family homes[citation needed], and within a short walk of the commercial areas of Center City.

In 2010, the Fitler Square Improvement Association engaged a large project at a cost of approximately $40,000 funded by neighborhood donations and a $7,000 grant from the Pennsylvania Horticultural Society to change the fountain into one that recirculates all of its water with a pumping system saving huge amounts of water each year.

The Philadelphia School, a private institution, is located in the Fitler Square Neighborhood at 2501 Lombard St.
