St. Stephens Indian School is a tribal K-12 school in St. Stephens, a settlement in Arapahoe, Wyoming. The school is affiliated with the Bureau of Indian Education (BIE).
A priest in a Jesuit order of the Catholic church established the school in 1884.
In 1985 there was a proposal to merge the school, then the St. Stephens Indian High School, with the Arapahoe School.
In 2015 the school created a documentary, "Listening For A New Day: the making of an Arapaho buffalo hide tipi," about its students creating tipis the traditional way. The documentary won the Red Nation Film Festival Oyate award.
