The Tamien people (also spelled Tamyen or Thamien) are one of eight linguistic divisions of the Ohlone people; groups of Native Americans who live in Northern California. The Tamien traditionally lived throughout the Santa Clara Valley. The use of the name Tamien is on record as early as 1777; it comes from the Ohlone name for the location of the first Mission Santa Clara (Mission Santa Clara de Thamien) on the Guadalupe River. Father Pena mentioned in a letter to Junipero Serra that the area around the mission was called Thamien by the native people. The missionary fathers erected the mission on January 17, 1777, at the native village of So-co-is-u-ka.
