The city of Sandy was originally settled by travelers passing along Barlow Road, one of the final sections of the Oregon Trail, and initially known as Revenue, after settlers Francis and Lydia Revenue. The city subsequently took the name Sandy after the Sandy River, named by Meriwether Lewis and William Clark in 1805; the river and previously been named the Barings River, after Sir Francis Baring, 1st Baronet, following a 1792 expedition in the region.

In the late 19th and early 20th centuries, Sandy's local economy was mainly based on logging and the sawmill industry due to the abundance of timber in the area. The city continued to grow with the arrival of German immigrants in the late 19th century, and the city was formally incorporated in 1911. In the latter half of the 20th century, the city's population saw a significant increase in residents, concurrent with the growth of the Portland metropolitan area.
