Itzamna (Mayan pronunciation: [it͡samˈna]) is, in Maya mythology, an upper god and creator deity thought to reside in the sky. Itzamna is one of the most important gods in the Classic and Postclassic Maya pantheon. Although little is known about him, scattered references are present in early-colonial Spanish reports (relaciones) and dictionaries. Twentieth-century Lacandon lore includes tales about a creator god (Nohochakyum or Hachakyum) who may be a late successor to him. In the pre-Spanish period, Itzamna was often depicted in books and in ceramic scenes derived from them. Before the names of the Maya deities were deciphered, Itzamna was known as "god D", and is still sometimes referred to as "god D" by archeologists.
