Fort Deshler, located near Egypt, Lehigh County, Pennsylvania, USA, was a French and Indian War era frontier fort established in 1760 to protect settlers from Indian attacks.

[1] The fort was near the location of what is now the intersection of Pennsylvania Route 145 and Chestnut Street, between Egypt and Coplay.

The fort was built by Adam Deshler, who was employed during the French and Indian War furnishing provisions for provincial forces.

[1] There appears to be no evidence that the fort was either garrisoned with provincial troops or served any military purpose beyond functioning as a place of refuge and rendezvous for settlers of the region.

[4] The historian Charles Rhoads Roberts, in his 1914 History of Lehigh County Pennsylvania and a Genealogical and Biographical Records of its Families, wrote the following about Fort Deshler: This old stone mansion, the only building standing in Lehigh County which was used as a fort in the colonial period, should by all means be preserved and marked as a historic spot, not only as a memorial to the pioneers of this location but also as a reminder to the coming generations of the hardships which their staunch and sturdy ancestors were compelled to undergo.Fort Deshler was not preserved, and stood in ruins until it collapsed around 1940.
