Tabscoob was a halach uinik (Maya ruler) of the Potonchán jurisdiction, known for leading the Chontal Maya in the Battle of Centla against Spanish forces led by Hernán Cortés on March 14, 1519.
Tabscoob's administration maintained commercial ties with the Mexicas and other Maya jurisdictions, especially with the jurisdiction of Chakán Putum, who—after having contact with the expeditions of Francisco Hernández de Córdoba and Juan de Grijalva—warned the Chontal to take precautions. On June 8, 1518, Juan de Grijalva landed in the province of Potonchán and met Tabscoob to whom, it is said, Grijalva gave his green velvet doublet.
