The Ritzville Carnegie Library, located in Ritzville, Washington, is a building listed on the National Register of Historic Places.

[3] It was built in 1907 with a grant from Andrew Carnegie and still operates as Ritzville's library.

It was designed by the Spokane architectural firm of Preusse & Zittel.

By 1906, the citizens of Ritzville had convinced Carnegie to help, and he pledged $10,000 toward a permanent library if the town secured and maintained a location for it.

At that time, Ritzville was the smallest town in the United States to receive financial assistance from Carnegie for a library.
