The Smithville Public School Building is a historic school building on Arkansas Highway 117 in the small community of Smithville, Arkansas.

It is a single-story T-shaped fieldstone structure with a cross-gable roof.

It was built in 1936 with funding from the Works Progress Administration in an attempt to bolster the community's economy, which had been affected by the Great Depression, and by the loss of its status as county seat when Sharp County was separated from Lawrence County.

[3] The building was listed on the National Register of Historic Places on January 11, 1993.
