Manada Gap is an unincorporated community in Dauphin County, Pennsylvania, United States, in the Harrisburg-Carlisle area, near Fort Indiantown Gap.
Distant about twelve miles from Fort Hunter is the passage through the Blue Range called Manada Gap, the next station in the chain occupied by the government. As in the case of Fort Hunter, the settlers about Manada Gap had already commenced a place of defense in the latter part of the fall of 1755. In February 1756, Captain Frederick Smith, with his company of provincials, either completed the fort already commenced or erected a new one. This was called Manada Fort.
