Korigad (also called Koraigad, Koarigad or Kumwarigad) is a hill fort located about 20 km (12 mi) south of Lonavla in Pune district, Maharashtra, India. Its date of construction is not known but likely predates 1500. It is about 923 m above sea level. The planned township of Aamby Valley is built over the fort's southern and eastern foothills. The closest village is Peth Shahpur, about 1 km (0.62 mi) north of the fort.
This fort was incorporated into his kingdom by the Maratha ruler Chatrapati Shivaji Maharaj along with the forts of Lohagad, Visapur, Tung and Tikona in 1657. On March 11, 1818, Colonel Prother tried to take over this fort but even after a prolonged siege could not make any headway. Finally on 14 March, by igniting the stored ammunition by means of a loose cannonball he succeeded and this fort went to the British.
