Dorseyville is an unincorporated suburb of Pittsburgh located in Indiana Township, Allegheny County, Pennsylvania, United States.

Dorseyville was originally called "Crowtown" by farmers, but later named for the Dorsey family that lived on modern day Cedar Run Road.

Records show the Lutheran and Reformer Church, the predecessor to Trinity United, purchased 50 square feet of land along Saxonburg Boulevard for $2 in 1851.

The church also received its charter as a religious organization that year and was named The First German Evangelical Lutheran Trinity Congregation of Dorseyville.

During the time of the deactivation, Pennsylvania Air National Guard 176th Artillery 2nd Missile Battalion was in control of the property.

During the Department Of Defense use, several improvements were made at the former launch and control areas including barracks, family housing units, mess halls, generator buildings, transformers, missile assembly and test building warhead storage, building an operations shelter, frequency changing buildings and control pad, three underground missile storage structures, four radar towers, missile tracking, acquisition tracking, target ranging, target tracking bore sighting, mast assembly tower, high power acquisition radar, HIPAR building and tower, POL building, radar and battery control trailers with permanent interconnecting corridor, sentry box buildings, and acid storage shed, fueling station and neutralizing pit, JP fuel pad, an above ground fuel oil tank, underground fuel storage tanks, canine kennel water storage tanks, pump houses and sewage systems septic tank, dosing chamber, distribution boxes, sand filters, hypochlorinator shelter, and a chlorine contact tank.
