The common or robust chimpanzee (Pan troglodytes), is a species of great ape.

The common chimpanzee is often called the chimpanzee (or "chimp"), but that may mean both species in the genus Pan: the common chimpanzee and the closely related bonobo.

Evidence from fossils and DNA sequencing show both species of chimpanzees are the closest living relatives to modern humans.

The common chimpanzee is more robust than the bonobo, weighing between 40 and 65 kg (88 and 143 lb) and measuring approximately 1.3 to 1.6 m (4 ft 3 in to 5 ft 3 in). Its gestation period is eight months. The infant is weaned at about three years old, but usually maintains a close relationship with its mother for several more years; it reaches puberty at the age of eight to 10, and its lifespan in captivity is about 50 years.
