Distribution and habitat The clouded leopard occurs from the Himalayan foothills in Nepal, Bhutan and India to Myanmar, southeastern Bangladesh, Thailand, Peninsular Malaysia, to south of the Yangtze River in China.

Since then, the clouded leopard has been recorded in Shivapuri Nagarjun National Park and in Annapurna Conservation Area.
