The views of Quakers around the world towards homosexuality encompass a range from complete celebration and the practice of same-sex marriage, to the view that homosexuality is sinfully deviant and contrary to God's intentions for sexual expression. The Religious Society of Friends (Quakers) is a historically Christian religious movement founded in 17th-century England; it has around 350,000 members. In Britain, Canada, New Zealand and Australia, many Quakers are supportive of homosexual relationships, while views are divided among U.S. meetings. Many Conservative Friends and Holiness Friends, both of which have retained traditional Quaker practices such as plain dress, along with Evangelical Friends, view homosexual acts as sinful. 49% of Quakers live in Africa, and though views may differ, the Kenyan Church of Friends does not support homosexual relationships.

Since Quaker decision making is generally based on seeking "unity" at the level of a Monthly meeting (convened periodically for business, and more often for worship, and is the basic unit of Quakerism – a meeting is equivalent to a single congregation, sometimes to a parish or group of churches in an area), determining a particular Quaker attitude is difficult on this or any topic. Monthly meetings are organized into larger groups such as Yearly meetings or other "umbrella" groups, but often these larger groups have conflicting stances on particular issues. Some groups, for example the 57th Street Meeting in Chicago, may have joint membership in umbrella groups that have mutually contradictory stances on the issues. In the end, the true "Quaker view" on homosexuality is probably best analysed meeting by meeting (or, better, Friend by Friend). However, there are some general patterns, and for reasons of space and completeness this article deals mainly with the largest organizations on a country-by-country basis. Until the 1960s the topic of homosexuality was untouched among Quakers. London Yearly Meeting's publication of Towards a Quaker View of Sex, including norms for sexual relations that were inclusive of equitable same-sex relations, provoked on-going questioning. By the time the first same-sex relationship was taken under the care of a Friends meeting in 1982 (University MM, North Pacific Yearly Meeting, Seattle, Washington) the scene was set for ongoing discernment and disagreement.

Quakers as a whole do not have a specific, set creed. The Richmond Declaration is a confession of faith that expresses the experience of two branches of American Quakerism, but does not reflect the views of others.

Quakers in Australia are overwhelmingly accepting of homosexuality and will celebrate same sex marriages as they would an opposite sex marriage. In 1975 Australia Yearly Meeting officially stated:

The Religious Society of Friends (Quakers) in Australia calls for a change in the laws ... to eliminate discrimination against homosexuals. This statement is made in the light of the Society's desire to remove discrimination and persecution in the community. The Society also calls on all people to seek more knowledge and understanding of the diversity of human relationships and to affirm the worth of love in all of them.

Australian Quakers have supported the celebration of same sex and different sex commitment ceremonies since 1994 and recognize them on an equal basis with other committed and loving relationships. In January 2010, Quakers meeting in Australia Yearly Meeting in Adelaide agreed to treat all requests for marriages in accordance with Quaker traditions, regardless of the sexual orientation or gender of the partners. Before this Australia-wide decision, Canberra Regional Meeting celebrated the first same sex marriage among Australian Quakers on 15 April 2007.

In New Zealand, the yearly meeting Te Hāhi Tūhauwiri, in 1992, resolved "to seek formal ways of recognizing a variety of commitments, including gay and lesbian partnerships".

Ireland Yearly Meeting, which includes meetings in Northern Ireland, permits same-sex marriages to take place within their meetings. However, no individual Friend or Meeting is required to take part in these marriages if it offends their conscience.
