The Tiwa or Tigua are a group of related Tanoan Puebloans in New Mexico. They traditionally speak a Tiwa language (although some speakers have switched to Spanish and/or English), and are divided into the two Northern Tiwa groups, in Taos and Picuris, and the Southern Tiwa in Isleta and Sandia, around what is now Albuquerque, and in Ysleta del Sur near El Paso, Texas.

Taos Pueblo (or Pueblo de Taos) is an ancient pueblo belonging to a Taos-speaking (Tiwa) Native American tribe of Puebloan people.

In the Southwestern United States, Pueblo (capitalized) refers to the Native tribes of Puebloans having fixed-location communities with permanent buildings which also are called pueblos (lowercased).
