Xlapak is a small Maya archaeological site in the Yucatan Peninsula of southeastern Mexico. It is located in the heart of the Puuc region, about 4 kilometres (2.5 mi) from the archaeological site of Labná and a similar distance from Sayil, lying directly between the two sites. It consists of three main groups in a valley of the Puuc Hills in Yucatán State, a region of karst limestone forming the only major topographical feature of the peninsula. The closest town is Oxkutzcab, about 30 kilometres (19 mi) to the northeast.

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.
