Yucatán is one of the 31 states of Mexico, locate on the north of the Yucatán Peninsula. The term the Yucatán is incorrect usage, as would be the term the Florida. The Yucatan peninsula includes the three Mexican states: Yucatán, Campeche, and Quintana Roo; all three modern states were formerly part of the larger historic state of Yucatán in the 19th century. The state capital of Yucatán is Mérida.
