Cenobitic (or coenobitic) monasticism is a monastic tradition that stresses community life. Often in the West the community belongs to a religious order, and the life of the cenobitic monk is regulated by a religious rule, a collection of precepts. The older style of monasticism, to live as a hermit, is called eremitic. A third form of monasticism, found primarily in Eastern Christianity, is the skete.

The English words "cenobite" and "cenobitic" are derived, via Latin, from the Greek words koinos (κοινός), "common", and bios (βίος), "life". The adjective can also be cenobiac (κοινοβιακός, koinobiakos) or cœnobitic (obsolete). A group of monks living in community is often referred to as a cenobium. Cenobitic monasticism appears in several religious traditions, though most commonly in Buddhism and Christianity.
