Tinigua (Tiniguas) is an endangered language isolate spoken in Colombia which used to form a small language family with the now extinct Pamigua language.

As of 2000, Tinigua had only two remaining speakers, Sixto Muñoz (Tinigua name: Sɨsɨthio ‘knife’) and his brother, Criterio. Criterio died some time around 2005, leaving behind Sixto as the last remaining speaker of Tinigua.^[2] Formerly a resident of the Serranía de la Macarena in Meta Department, Sixto Muñoz currently resides in Jiw village of Barrancón, near the main town of Guaviare Department.^[3]: 1029 They lived in Meta Department, between the Upper Guayabero and Yari rivers.^[4]

Muñoz also speaks Spanish and is thought to have been born somewhere from 1924-1929. He has five children, but he chose not to teach them Tinigua because they would not have any use for it.^[5]

Below is a comparison of Tinigua forms elicited from Sixto Muñoz in 2019 compared with Tinigua and Pamigua words recorded in Castellví (1940).^[6][3]
