Khammam Fort is a fort in the city of Khammam, Telangana, India constructed by Musunuri Nayaks. It served as an impregnable citadel during various regimes of different dynasties, including the Musunuri Nayaks, Qutb Shahi’s, and Asaf Jahis. The fort was situated in a very vast area in the heart of the City of Khammam. It was notified as a protected monument by the Archaeology Department several decades ago. Despite decades of neglect, the historical edifice, which once flourished with regal opulence, presents its alluring charm due to its architectural splendor.

The Khammam Fort was built by Musunuri Nayaks. Several inscriptions were discovered in the surrounding areas of Khammam and Krishna districts of Musunuri Nayaks. Khammam slowly became an independent territory within the kingdom of Kakatiyas for Musunuri Nayaks. 75 Telugu speaking feudatories of the region under the leadership of Musunuri Nayaks fought for 10 long years to unify the Telugu land and succeeded in repulsing the Delhi Sultanate forces under Malik Maqbul (Khan-e-Jahan Tilangani) out of their country.
