Humboldt Public Library in Humboldt, Iowa, USA, is a free public library. The library received a $10,000 grant from the Carnegie Corporation of New York on December 13, 1906. The Des Moines architectural firm of Hallett & Rawson designed the building. It was built using limestone from a nearby area now known as Taft Park. Construction began in 1908 and it was dedicated on February 9, 1909. The rough texture of the rock-faced stone and the portico columns in the Tuscan order give the building a rustic appearance. It was listed on the National Register of Historic Places in 1983. A north entrance and extension were added to the building in 1992.
