Horsfield's fruit bat (Cynopterus horsfieldii) is a species of megabat native to South East Asia.

Adults weigh around 55 to 60 grams (1.9 to 2.1 oz), and have light-grey to brown fur, with a reddish-brown or orange mantle around the shoulders.

Within this region, it inhabits a broad range of lowland habitats, from dense primary rain forest to agricultural land and suburban gardens.

During the dry season, when fruit is in short supply, they instead feed on pollen, which they take from a wide variety of plants.

They often modify their roosting sites by constructing tents from the leaves, partly cutting through them to make an inverted "V" shape.
