The Asian palm civet (Paradoxurus hermaphroditus), also called common palm civet, toddy cat and musang, is a viverrid native to South and Southeast Asia. Since 2008, it is IUCN Red Listed as Least Concern as it accommodates to a broad range of habitats. It is widely distributed with large populations that in 2008 were thought unlikely to be declining. It is threatened by poaching for the illegal wildlife trade.

The Asian palm civet's long, stocky body is covered with coarse, shaggy hair that is usually greyish in colour. It has a white mask across the forehead, a small white patch under each eye, a white spot on each side of the nostrils, and a narrow dark line between the eyes. The muzzle, ears, lower legs, and distal half of the tail are black, with three rows of black markings on the body. Its head-to-body length is about 53 cm (21 in) with a 48 cm (19 in) long unringed tail. It weighs 2 to 5 kg (4.4 to 11.0 lb). Its anal scent glands emit a nauseating secretion as a chemical defense when threatened or upset.^{[page needed]}

The Asian palm civet is widely distributed in South and Southeast Asia, ranging from India, Nepal, Bangladesh, Bhutan, Sri Lanka to Myanmar, Thailand, Peninsular Malaysia, Singapore, Laos, Cambodia, Vietnam, China, the Philippines, Borneo and the Indonesian islands of Sumatra, Java, Bawean and Siberut. It usually inhabits primary forests, but also occurs at lower densities in secondary and selectively logged forest.

The Asian palm civet was introduced to Irian Jaya, the Lesser Sunda Islands, Maluku, and Sulawesi. Its presence in Papua New Guinea is uncertain.

The Asian palm civet is thought to lead a solitary lifestyle, except for brief periods during mating. It is both terrestrial and arboreal, showing a nocturnal activity pattern with peaks between late evening until after midnight. It is usually active between dawn and 4:00 in the morning, but less active during nights when the moon is brightest.

Scent marking behaviour and olfactory response to various excretions such as urine, feces, and secretion of the perineal gland differs in males and females. Scent marking by dragging the perineal gland and leaving the secretion on the substrate was most commonly observed in animals of both sexes. The duration of the olfactory response varied and depended both on the sex and excretion type. The palm civet can distinguish animal species, sex, familiar and unfamiliar individuals by the odor of the perineal gland secretion.

The Asian palm civet is an omnivore feeding foremost on fruits such as berries and pulpy fruits. It thus helps to maintain tropical forest ecosystems via seed dispersal. It eats chiku, mango and rambutan, but also small mammals and insects. It plays an important role in the natural regeneration of Pinanga kuhlii and P. zavana palms at Gunung Gede Pangrango National Park.

Due to its solitary and nocturnal habits, little is known about its reproductive processes and behaviour. In March 2010, a pair of palm civets was observed when attempting to mate. The pair copulated on the tree branch for about five minutes. During that period, the male mounted the female 4–5 times. After each mounting, the pair separated for a few moments and repeated the same procedure. After completion of mating, the pair frolicked around for some time, moving from branch to branch on the tree. The animals separated after about six minutes and moved off to different branches and rested there.
