El Palma, known anciently as Lakamtuun, is an archaeological Maya site located in the Lacantún river of Chiapas in Mexico.

El Palma or Lakamtuun was an ancient Mayan state of the Classic period that ruled a part of the western territory of the Usumacinta Basin along the Lacantún River.

[1] The kingdom of Lakamtuun developed during the Classic period in the Usumacinta Basin on the banks of the Lacantún River in constant political and military conflicts for the domination of the region by major powers such as Yaxchilán and Piedras Negras.

[2] On Piedras Negras panel 12, a victory of the local dynasty over several cities is shown, including the capture of four important captives, one of them identified as the ruler of Lakamtuun named Ahiin Chan Ahk.

[3] In Yaxchilán, K'ihnich Tatb'u Jol II began conquering sites along the Usumacinta and expanding its influence to other regions through military conflicts.
