The People's Federal Savings and Loan Association is a historic bank building at 101 East Court Street in Sidney, Ohio, designed by Chicago architect Louis Sullivan. It was designed and built in 1917 for use by Peoples Federal Savings and Loan Association, which still operates out of it. It is one of a handful of banks designed by Sullivan between 1908 and 1919 for small communities in the central United States. The building is a National Historic Landmark.

People's Federal Savings and Loan Association is located at 101 East Court Street on the corner of South Ohio Street in Sidney across from the Spot restaurant. It lies also across the street from the Gothic revival Monumental Building and the Second Empire-style Shelby County Courthouse. Numerous colors adorn the building, beginning with the corbels of multicolored terracotta, which are placed over the front windows. A dominant Romanesque Revival archway forms the main entrance, set in a building base of black marble and amid walls of strong reds. Other parts of the walls are pierced by numerous windows featuring blue, green, and purple glasswork. The design is the result of Sullivan's architectural ideal: simple structurally but ornately decorated in their details.

The Sidney People's Federal Savings and Loan Association was one of a series of commissions that architect Louis Sullivan took on late in his career. These commissions resulted in a collection of bank buildings that have been termed "jewel boxes" for their modest size and ornate appearance. According to one account of the creation of Sullivan's design, he produced a sketch of it after two days of observing the empty lot where it was to stand. The sketch was at first rejected by the bank directors, who expressed a desire for a more conventional design with Classical features. Sullivan observed that they could have hired any of "a thousand architects to design a classic bank", but that only he could produce this type of design. The building was completed for $1,000 less than Sullivan's estimated cost.
