Beacon Press is an American left-wing non-profit book publisher. Founded in 1854 by the American Unitarian Association, it is currently a department of the Unitarian Universalist Association. It is known for publishing authors such as James Baldwin, Mary Oliver, Martin Luther King Jr., and Viktor Frankl, as well as The Pentagon Papers.

Unitarian Universalist Association (UUA) is a liberal religious association of Unitarian Universalist congregations. It was formed in 1961 by the consolidation of the American Unitarian Association and the Universalist Church of America Christian denominations with Unitarian and Universalist doctrines, respectively. However, modern Unitarian Universalists see themselves as a separate religion with its own beliefs and affinities. They define themselves as non-creedal, and draw wisdom from various religions and philosophies, including humanism, pantheism, Christianity, Hinduism, Buddhism, Taoism, Judaism, Islam, and Earth-centered spirituality. Thus, the UUA is a syncretistic religious group with liberal leanings.
