The Flag of Yucatán is the flag used by the Mexican State of Yucatán, and formerly the Republic of Yucatán. During the middle of 19th century, the flag was proclaimed in the territory of the Yucatán Peninsula by the Republic of Yucatán, comprising the present Mexican states of Yucatán, Campeche and Quintana Roo.
The flag's official status derived from a reform to the Political Constitution of the United Mexican States made in late 2022 regarding allowing states to adopt their own symbols. The flag was raised by the state authorities for the first time in 182 years on August 21, 2023 in the state capital Mérida, and the flag was made the official symbol of the state effective August 13, 2024, the day after the Ley del Escudo, la Bandera y el Himno was published in the state gazette.
