History
The name Sasabe is derived from the Native American language of the Tohono O'odham (formerly Papago) meaning "head valley". The post office was established at Sasabe in 1905.

Sasabe is best known for its historic Rancho de la Osa guest ranch, formerly the headquarters of a three million acre (12,000 km2) Spanish land grant. Some ranch buildings reportedly date to the late 17th century. The guest ranch opened in 1921. Guests have included Presidents Franklin Roosevelt and Lyndon Johnson.

On average, 165 cars, trucks, or pedestrians per day passed through the Sasabe Port of Entry in 2011. Sasabe, Arizona is smaller than its sister community, El Sásabe, Sonora, which is known for its burnt-adobe brickyards.

In the 2018–2019 school year, the local school served 28 children in grades K-8.
