The Union Town Company established the town of Waldo on October 1, 1888, having acquired 280 acres of land on a line of the Union Pacific Railroad. The community grew over the following decades, reaching a population of approximately 300 by 1915. A small business community, including a bank, stores, and three grain elevators, developed during the 1900s. The town served as an agricultural shipping and receiving point for the surrounding area. Waldo incorporated as a city in May 1911.
Since the 1930s, the population of the community has gradually declined. Waldo High School closed in 1964, followed by Waldo Grade School in 1979. In 1993, Union Pacific abandoned its rail line through Waldo, ending rail service to the community.
