Gajner Wildlife Sanctuary, Wildlife refuge in Bikaner district, India.

Gajner Wildlife Sanctuary is a refuge in Bikaner district with a lake that draws many animal species to the area. The habitat supports deer, antelope, nilgai, and desert foxes.

The refuge began as a hunting ground for the Maharaja of Bikaner during British rule. It was later transformed into a protected area.

The site remains connected to regional heritage through the adjacent Gajner Palace, built by Maharaja Sir Ganga Singh in the late 1800s. The palace and refuge shape the area's cultural landscape together.

The site lies about 32 kilometers from Bikaner and is best visited between October and March when temperatures are comfortable. These months provide the best conditions for wildlife observation.

The lake was dug artificially at the foot of the Maharaja of Bikaner's summer palace, and the forest around it gives way to savanna that ends in desert. Gajner is also one of the forests proposed for reintroducing cheetahs to India.
