The area was first known as "Sand Hill" when it was settled by farmers in the late 18th century. The present community grew up around the "Prospect" railroad station erected by the Louisville, Harrods Creek and Westport Railway. The name referred either to the view from the top of the hill or the expected completion of the line. When the post office was established in 1886, the local postmaster named it "Wilhoyte" in his own honor, but the community corrected this within the month. Although a few luxury residences existed in the area from the late 19th century and the Louisville Railway Company offered hourly electrified-rail trolleys along the former LHC&W line after 1904, it was largely agricultural until the mid-1960s when large, high-end subdivisions were built in the area, most notably Hunting Creek, which included a golf course. Prospect incorporated as a city in 1974.
