Jaina Island is a pre-Columbian Maya archaeological site in the present-day Mexican state of Campeche. A small limestone island on the Yucatán Peninsula's Gulf coast with only a tidal inlet separating it from the mainland, Jaina served as an elite Maya burial site, and is notable for the high number of fine ceramic figurines excavated there.
The term "Jaina" translates to "Temple in the Water".
