Jumaca (born c. 1480s) was the Taíno Cacique (Chief) of the area in Puerto Rico named after him (now spelled Humacao).
[1][self-published source] According to the "Chronicles of the Indias", which are kept in Seville, Spain, in February 1511, Agueybana's brother Güeybaná, better known as Agüeybaná II (The Brave), Urayoan, the Cacique of Añasco and some of their men drowned the Spanish soldier Diego Salcedo.
After Ponce de León's troops killed the Cacique Agueybana II, the Spanish Government reached an agreement and signed a peace treaty.
According to the testimony of Ignacio Martinez, the sole survivor of the "Santiago incident", the Caciques and their tribes hid in the Sierras (mountains) of Luquillo.
The City of Humacao also presents the "Cacique Jumacao Award" to the best industries in regard to its recycling programs.
