Itza' (also Itza, Petén Itzá Maya) is one of the Yucatecan branch of the Mayan languages. The other languages in the Yucatecan branch are Yucatec, Lakantun, and Mopan. All the Yucatecan languages are closely linked with each other. However, people speaking Itza' and those speaking Yucatec do have difficulties understanding each other.
Today, it is spoken only by a few elderly adults in communities to the north of Lake Petén Itzá in northern Guatemala. It is nearly extinct. The Itza ethnic group now almost all speak Spanish, and are not fluent in Itza'.
