Surgad is a hill fort located in a spur, fragmented from the Sahyadri ranges of Maharashtra. The fort is situated near Roha, next to the village of Gherasurgad in the Raigad district. This fort was an observation fort, which guarded the trade route along the Kundalika river from Sudhagad to Revdanda fort.

This fort is believed to be built by Shilahar kings and subsequently used by the Nizam of Ahmednagar. The great Maratha king Chhatrapati Shivaji is also believed to have reconstructed this fort. During the Rajaram's regime this fort was captured by Shankarji Narayan Sachiv from the Siddhi of Janjira. In 1733 again this fort was captured by Senior Bajirao I. During Peshwa period this fort was used to keep prisoners. There is a block of stone with inscriptions in Farsi (Persian) and Devnagari. The inscription records that the fort was built in the beginning of the second year of the command of Sidhi saheb. The architect was Nuryaji and the Governor of the fort was Tukoji Haibat. It seems that the fort was built at times when use of artillery was not known in battle. In the Third Anglo-Maratha War, along with other forts in the neighboring region.this fort was won over by Colonel Prother from the Peshwas in February 1818.
