Richland Junction is a neighborhood of Richland in Benton County, Washington, United States. It is located within the east city limits of Richland.
Original known as Chemna, Richland Junction was founded in 1900 by Benjamin Rosencrance, a settler who purchased land from the Northern Pacific Railway Company for use as the Benton Post Office. The name was changed to Richland in honor of Nelson Rich in 1905. Rich, a state legislator from Prosser, and a partner in an irrigation company, helped secure the townsite.
