Westerville is an unincorporated community and census-designated place in Custer County, Nebraska, United States.

[4] Westerville was named for James Westervelt, a local storekeeper on whose land the townsite was platted August 11, 1880.

Along with the post office, the town was home to sod houses, a hotel, blacksmith shop, livery barn, and flour mill.

When a railroad was built farther south of Westerville in 1886, the town gradually declined.

[9] Westerville was the nearest town to John W. Speese (1866-1914), an African American farmer who homesteaded there in 1881.
