The Tahamí (Spanish: Terreno Tahamí, TT) or Tahamí-Panzenú Terrane is one of the geological provinces (terranes) of Colombia. The terrane, dating to the Permo-Triassic, is situated on the North Andes Plate. The contact with the Chibcha, Arquía and Quebradagrande Terranes is formed by the megaregional Romeral Fault System. A tiny terrane is located at the contact with the Quebradagrande Terrane; Anacona Terrane.

The terrane is offset along the regional Bucaramanga-Santa Marta Fault from the Caribbean, La Guajira and Chibcha Terranes, and by the regional Oca Fault with the Chibcha Terrane.

The terrane is, as the Chibcha Terrane, named after an indigenous people from Antioquia; the Chibcha-speaking Tahamí [es], part of the greater Nutabe group. Panzenú refers to the Zenú civilization, that thrived from about 200 BCE to 1600 CE in the Sinú river basin.

A study performed by Mora Bohórquez et al. in 2017 showed no basement variation between the Chibcha Terrane San Lucas basement underlying the Lower Magdalena Valley (VIM) and the SNSM basement to the east of the Santa Marta Fault. The authors redefined the contacts between the different terranes, using the names Calima Terrane for the coastal portion of the Caribbean Terrane (San Jacinto and Sinú foldbelts) and Tahamí-Panzenú Terrane for the Tahamí Terrane.
