Oljato Trading Post, Trading post in Oljato-Monument Valley, United States.

Oljato Trading Post is a trading establishment in the Monument Valley region of Utah comprising several connected structures. The building features a central trading room, storage areas, living quarters, and a traditional hogan building that together formed a functional commercial complex from the early 20th century.

The trading post was founded in 1906 by John and Louisa Wade Wetherill, who brought supplies by horse-drawn wagon from Gallup, New Mexico, a 21-day round trip. The present structure was built in 1921 by licensed trader Joseph Hefferman, who sold it in 1936. It was added to the National Register of Historic Places on June 20, 1980, and stabilized in 2020.

The trading post served as a gathering place where Navajo artisans could display and sell handmade goods such as jewelry, pottery, and woven textiles. This location held significance in the daily lives of the local community and allowed visitors to acquire authentic crafted items directly from the makers.

The site lies on the western edge of Oljato–Monument Valley in San Juan County, Utah, reached by unpaved roads that become difficult in rain or snow. The structures were stabilized in 2020 by the State Historic Preservation Office and the Navajo Nation Historic Preservation Department, so access to the interior may be limited.

The name comes from the Navajo word Oljéé'to meaning Moonwater, a reference connected to the location itself. This naming choice reflects the deep tie between local culture and the surrounding land that remains visible to this day.
