The Hiram C. Stewart House is a historic Prairie School house designed by George W. Maher located at 521 Grant Street in Wausau, Wisconsin.

It is generally Prairie Style, with horizontal lines and broad eaves.

Themes of a tulip and a tripartite arch repeat both inside and out, exemplifying Maher's "motif rhythm theory" of design.

[2] The house currently serves as a bed and breakfast called the Stewart Inn.
