Puuc is the name of either a region in the Mexican state of Yucatán or a Maya architectural style prevalent in that region. The word "puuc" is derived from the Maya term for "hill". Since the Yucatán is relatively flat, this term was extended to encompass the large karstic range of hills in the southern portion of the state, hence, the terms Puuc region or Puuc hills. The Puuc hills extend into northern Campeche and western Quintana Roo.
