Lucknow is an unincorporated American community and neighborhood that is located in Susquehanna Township, Dauphin County, Pennsylvania, United States, in the Harrisburg-Carlisle area.

[1] Lucknow is roughly bounded to the north by Rockville and Blue Ridge Road in upper Susquehanna Township; east to Fargreen Road, west along Linglestown Road straddling the Harrisburg/Susquehanna Township line, south to Lucknow Road, east to the Harrisburg Intermodal Yard along North Sixth Street and west to Front Street.

The area was named after Lucknow, Uttar Pradesh, India where the Indian Rebellion of 1857 took place between Indian freedom fighters and the East India Company army.

Late in the 19th Century, Reily moved to work on a dairy farm at Fort Hunter and sold the forge to the Pennsylvania Railroad as the site of a rail welding plant next for their expanding rail yard.
