The primate family that includes humans, chimpanzees, gorillas, and orangutans is Hominidae.
Hominidae is the zoological family commonly called the great apes, or hominids. Its four living genera are Homo (humans), Pan (chimpanzees and bonobos), Gorilla (gorillas), and Pongo (orangutans). The family also includes numerous extinct relatives known from the fossil record.
The classification reflects evolutionary relationships rather than appearance alone. Orangutans form the subfamily Ponginae, while humans, chimpanzees, bonobos, and gorillas belong to Homininae. Gibbons are apes too, but they are the “lesser apes” in the separate family Hylobatidae.
A common mix-up involves the words hominid and hominin. In modern usage, hominid includes all great apes, humans included. Hominin is narrower and generally refers to humans and their closer extinct relatives after the human lineage split from the chimpanzee lineage. The family name Hominidae was established by John Edward Gray in 1825.
