Rathdrum is situated at the base of Rathdrum Mountain, which is part of the Selkirk Mountain Range.

In the 1800s the town was initially called Westwood in honor of one of the founders of the town, a Pony Express rider and rancher, Charles Wesley Wood, also known as "Wes." But in 1881 the postmaster in the town was informed by the federal government that the town would need to change its name since it was already taken by another town in the territory. A local businessman, Michael M. Cowley, recommended the name "Rathdrum" from County Wicklow in Ireland, his place of birth.

Near the end of the 19th century, the Northern Pacific Railway built its line westwards to Spokane and Rathdrum started to grow slowly. Until today, Rathdrum remains on the only regular railway line in Idaho, now owned by BNSF Railway; the Empire Builder of Amtrak travels through Rathdrum without stopping there.
