Homún Municipality (Spanish pronunciation: [xoˈmun], in the Yucatec Maya language: “Five unripened”) is a municipality in the Mexican state of Yucatán containing (192.89 km) of land and located roughly 50 km southeast of the city of Mérida.

After the conquest, during the colonial period, the Municipality of Homún was founded as an encomienda first for Pedro Alvarez y Melchor Pacheco in 1549; Juan Vela in 1564; Juan Vela de Aguirre, Catalina de Rua and Santillán Gómez del Castillo in 1579; Pedro de Mézquita in 1629; Cristóbal Gutiérrez Flores, Juan del Castillo y Quiñones and Juan Serrano in 1687; Ana Serrano and Alonso de Aranda y Aguayo in 1710, who had control of 162 Indians; and finally Antonio del Castillo y Carrillo in 1725 who controlled 469 Indians.
