Krishna Wildlife Sanctuary, Wildlife sanctuary in Andhra Pradesh, India

Krishna Wildlife Sanctuary is a protected area in the Krishna River delta region, encompassing wetlands, mudflats, and mangrove forests. The space includes different habitat types that support both migratory and resident wildlife species.

The area received official protection in 1996 to safeguard the wetland ecosystems. This action created an important corridor for native and migratory species across the delta region.

Hindu and Jain pilgrims visit the area because tradition links it to the second avatar of Vishnu. Under Salarjung rule in the 18th and 19th centuries, the delta also served as a port town and as a refuge for people fleeing drought and famine.

The sanctuary lies in the Krishna River delta across Krishna and Guntur districts, between 15°2'N and 15°55'N and 80°42'E and 81°01'E. It is reached by road via the Kakinada-Vizag and Gannavaram-Machilipatnam national highways. A separate mangrove patch stands east of Machilipatnam and west of Nakshatranagar, apart from the main forest block.

The sanctuary houses more than 300 bird species and serves as critical habitat for the Indian marsh crocodile in its tidal estuaries. These crocodiles make their home in the shallow waters and are seen regularly by visitors.
