Religious vows are the public vows made by the members of religious communities pertaining to their conduct, practices, and views.

In the Buddhism tradition, in particular within the Mahayana and Vajrayana tradition, many different kinds of religious vows are taken by the lay community as well as by the monastic community, as they progress along the path of their practice. In the monastic tradition of all schools of Buddhism, the Vinaya expounds the vows of the fully ordained Nuns and Monks.

In the Christian tradition, such public vows are made by the religious – cenobitic and eremitic – of the Catholic Church, Lutheran Churches, Anglican Communion, and Eastern Orthodox Churches, whereby they confirm their public profession of the evangelical counsels of poverty, chastity, and obedience or Benedictine equivalent. The vows are regarded as the individual's free response to a call by God to follow Jesus Christ more closely under the action of the Holy Spirit in a particular form of religious living. A person who lives a religious life according to vows they have made is called a votary or a votarist. The religious vow, being a public vow, is binding in Church law. One of its effects is that the person making it ceases to be free to marry. In the Catholic Church, by joining the consecrated life, one does not become a member of the hierarchy but becomes a member of a state of life which is neither clerical nor lay, the consecrated state. Nevertheless, the members of the religious orders and those hermits who are in Holy Orders are members of the hierarchy.
