The Crab-eating macaque, Long Tailed Macaque, or Macaca fascicularis is a cercopithecine primate native to Southeast Asia.

It is referred to as the cynomolgus monkey in laboratories. A species of macaque, the crab-eating macaque has a long history alongside humans; it has been alternately seen as an agricultural pest, sacred animal in some temples, and more recently, the subject of medical experiments.

The Crab-eating macaque or Macaca fascicularis lives in matrilineal social groups of up to eight individuals dominated by females. Male members leave the group when they reach puberty.

It is an opportunistic omnivore and has been documented using tools to obtain food in Thailand and Myanmar. They are an invasive species and a threat to biodiversity in several locations, including Hong Kong and western New Guinea.

The body length of the adult, which varies among subspecies, is 15–22 in. with relatively short arms and legs. Males are considerably larger than females, weighing 11–20 lb. compared to the 6.6–13.2 lb. of females.

The tail is longer than the body, typically 16–26 in., which is used for balance when they jump distances up to 16 ft. The upper parts of the body are dark brown with light golden brown tips. Macaca fascicularis under parts are light grey with a dark grey brown tail.

Crab-eating macaques or Macaca fascicularis have backwards-directed crown hairs which sometimes form short crests on the midline.

Their skin is black on their feet and ears, whereas the skin on the muzzle is a light grayish pink color. The eyelids often have prominent white markings and sometimes there are white spots on the ears.

Males have a characteristic mustache and cheek whiskers, while females have only cheek whiskers. Crab-eating macaques or Macaca fascicularis have a cheek pouch which they use to store food while foraging.
