The Northern Tiwa Picuris are a Native American people of related Tanoan pueblo peoples in New Mexico and who reside on the Picuris Pueblo and Taos Pueblo. They traditionally spoke a Tiwa language (although some speakers have switched to Spanish and/or English). They are related to the Southern Tiwa in Isleta and Sandia, around what is now Albuquerque.

During Powwows they perform the Sun Dance. The Sun-moon dance lasts for a period of four days in which participants dance backwards and forwards to a ceremonial tree in the centre of an Arbour. During this period they abstain from food and water. This is spiritual ceremony.

A large percentage of Northern Tiwa adhere to Roman Catholicism. A small percentage are evangelical Christians. Many, in practice, adhere to traditional religious beliefs and animistic practices.
