Sanjay Gandhi National Park is an 87 km2 (34 sq mi) protected area in Mumbai, Maharashtra.

The rich flora and fauna of the Sanjay Gandhi National Park attract more than 2 million visitors every year.

The same year, some forests from the Thane division were merged into the park, further expanding its total area to 103.84 km2 (40.09 sq mi).
