Oxkintok is a pre-Columbian Maya archaeological site on the Yucatán Peninsula, located at the northern tip of the Puuc hills - a few kilometers to the east of the modern town of Maxcanú, Yucatán, Mexico.

In the Maya language, the name "Oxkintok" can be parsed as "Ox" (three) and "Kin" (day/sun), but there are multiple possibilities for "Tok" (if the final letter is a soft /K/ then it may mean "snatch away / defend, lean, fall, or burn", but if the final letter is truly a glottalized /K’/ then it may mean "puncture, let blood, or chert / flint / hard stone"). Different translations, based upon the various meanings of "Tok" are found in the literature.

The site has provided evidence of habitation from the Late Preclassic through the Late Postclassic periods of Maya prehistory. However, Oxkintok became a major center between the Early Classic and Terminal Classic periods (including what Carmen Varela terms the "Middle Classic"). It is well known as possessing a very early Long Count date in AD 475 (on the lintel of Structure 6 in the "Canul" group). The latest dated monument at the site records a date in AD 859.
