Friends United Meeting (FUM) is an association of twenty-six yearly meetings of the Religious Society of Friends (Quakers) in North America, Africa, and the Caribbean. Its home page states that it is "a collection of Christ-centered Quakers, embracing 34 yearly meetings and associations, thousands of local gatherings and hundreds of thousands of individuals". In addition there are several individual monthly meetings and organizations that are members of FUM; FUM's headquarters is in Richmond, Indiana, with offices in Kisumu, Kenya. Friends United Meeting is a member of the National Council of Churches in the United States of America, and is a global member of the World Council of Churches.

There are five other branches within American Quakerism, of which two are represented by similar international organizations^{[citation needed]} (Friends General Conference and Evangelical Friends Church International), one is represented by a single yearly meeting (Central Yearly Meeting of Friends), and two (Conservative Friends and Beanite Quakerism) have no single unifying organization.

After the switching of around 7,000 Friends in California to the EFCI, FUM is the second largest association of Friends in the United States. As of 2010, there were 24,826 members in 258 congregations in the United States. The Friends United Meeting is responsible for much of the growth of Quakerism in Africa and Latin America. Globally, FUM has over 170,000 members, with 75 percent of the Monthly meetings being in Kenya.

FUM has meetings in the United States, Canada, Belize, Cuba, Jamaica, Kenya, Tanzania, and Uganda. FUM is also affiliated with the only Quaker meeting in Palestine, the Ramallah Friends Meeting.

15 years after the signing on the Richmond Declaration in 1887, Five Years Meeting was established in 1902 by a collection of orthodox yearly meetings.

After World War I, growing desire for a more fundamentalist approach began to split Five Years Meeting. In 1926, Northwest Yearly Meeting withdrew from the organization, leading several other yearly meetings and scattered monthly meetings. In 1947, the Association of Evangelical Friends was formed, which led in turn to the 1965 formation of the Evangelical Friends Association, a precursor to today's Evangelical Friends International, formed in 1989.

During the 1950s many yearly meetings in North America reunited and became joint members of Five Years Meeting and Friends General Conference.

In 1963 Five Years Meeting was renamed Friends United Meeting.
