The William Shelly School and Annex, also known as the Eberton School, is a historic school building and annex located in West York, York County, Pennsylvania. Built circa 1897, the Shelly Annex was initially designed as a one-room school, but was then enlarged twice between 1898 and 1903 to become a 2 1/2-story, gable roofed brick building which is three bays wide and seven bays deep. Built between 1905 and 1908, the Shelly School was designed in the Italian Renaissance style, and is a two-story brick structure which is nine bays wide and seven bays deep. Completely rebuilt following a fire in 1919, the property was sold in 1960; the buildings were then utilized as storage facilities for the next 37 years.
