Tinúm Municipality (Yucatec Maya: "crippled numtzutzuy[n 1]")[5] is a municipality in the Mexican state of Yucatán containing (393.44 km2 or 151.91 sq mi) of land and is located roughly 140 kilometres (87 mi) east of the city of Mérida.

[2] There is no accurate data on when the town was founded, but it was a settlement before the conquest and was located in the chieftainship of Cupules.

Within the municipality is Chichen Itza, a city built in the Post Classic Maya period, which reached its apex between the 11th and 12th centuries.

After colonization by the Spanish, the area became part of the encomienda system with various encomenderos,[2] beginning with Juan García de Llanos in 1549 and passing to the crown in 1551.

The town council has seven councilpersons, who serve as Secretary and councilors of public works, police commissaries, education, ecology, public monuments and sports.
