Charles Mason Remey was a prominent member of the early American Baháʼí community, and served in several important administrative capacities. He is well-known for an attempted schism of 1960, in which he claimed leadership and was rejected by the overwhelming majority of Baháʼís, who regard him as a Covenant-breaker.

The Baháʼí Faith was first mentioned in the United States in 1893 at the World Parliament of Religions in Chicago. Soon after, early American converts began embracing the new religion. Thornton Chase was the most prominent among the first American Baha'is and made important contributions to early activities. One of the first Baháʼí institutions in the U.S. was established in Chicago and called the Baháʼí Temple Unity, incorporated in 1909 to facilitate the establishment of the first Baháʼí House of Worship in the West, which was eventually built in Wilmette, Illinois and dedicated in 1953. As of 2020 the Association of Statisticians of American Religious Bodies noted the Baháʼí Faith was the largest non-Christian religion in the majority of US counties.
