The Tiwa or Tigua are a group of related Tanoan pueblo peoples in New Mexico and Texas.

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 near El Paso.
