Te' K'ab Chaak ("Tree Branch Rain God") was a Mayan king (ajaw) of Caracol in Belize. He was a founder of the Caracol dynasty.
Two retrospective references to Te' K'ab Chaak in Late Classic texts place him in the middle of the fourth century AD; that a king from this early era should continue to be talked about hundreds of years later suggests that he was the dynasty founder.
Marc Zender cautions that the translation of Te' K'ab Chaak's name as "Tree Branch Rain God" is unlikely, given that k'abte' (literally "arm (of) tree"), rather than te'k'ab, would be the expected order of elements in Mayan for the meaning "tree branch".
Zender suggests a translation like "Tree-Armed Chaak" or "Trees are the Arms of Chaak".
