La Réunion was a utopian socialist community formed in 1855 by French, Belgian, and Swiss colonists near the forks of the Trinity River in the U.S. state of Texas. The Reunion Tower in downtown Dallas is about three miles east of the colony site. The founders of the community were inspired by the utopian thought of the French philosopher François Marie Charles Fourier. Followers of Fourier established 29 similar colonies in various parts of the United States during the 19th century. In 1860 the declining colony was incorporated into the expanding city of Dallas.
