This is a list of Fourierist Associations in the United States which emerged during a short-lived popular boom during the first half of the 1840s. Between 1843 and 1845 more than 30 such "associations" – known to their adherents as "phalanxes" – were established in the United States, all of which met with economic failure and rapid disestablishment within one or a comparatively few years.
The Fourierist movement of the 1840s was one of the four primary branches of secular utopian socialism in the United States during the 19th century, succeeding Owenism (1825–27) while antedating Icarianism (1848–98) and Bellamyism (1889–96).
