The Ringgold County Courthouse in Mount Ayr, Iowa, United States, was built in 1927.

It was listed on the National Register of Historic Places in 1981 as a part of the County Courthouses in Iowa Thematic Resource.

A frame building was constructed for the second courthouse and the county paid $3,500 to have it built.

[2] It was designed by the Des Moines architectural firm of Keffer & Jones and built by the L.T.

The courthouse is considered a "budget classical" building by which the structure's Beaux-Arts and Neoclassical design elements are stripped to a minimal form.
