Prabalgad (also known as Muranjan, Pradhangad or Prabalmachi) is a fort located between Matheran and Panvel and comes under the Raigad District in the state of Maharashtra, India.

During the collapse of the Ahmadnagar Sultanate, Shahaji led a helping hand against the separate forces of the Mughal Empire and the Adil Shahi dynasty.

However, following Shahaji's defeat and the agreement of Mahuli, North Konkan along with the fort, was ceded to Mughals who granted ruling authority of the area to Adilshah of Bijapur.

[8][9] In the year 1826, Umaji Naik, a freedom fighter and his associates were believed to have made the fort as their home for a brief period of time.

[citation needed] Prabalgad lies on the Prabal plateau between Matheran and Panvel and can be easily spotted from the Mumbai-Pune expressway.
