The Hughes County Courthouse, located on Capitol Avenue in Pierre, is the center of government of Hughes County, South Dakota. The courthouse was built from 1934 to 1935, replacing a building built in 1883. Architects Hugill & Blatherwick designed the building in the Moderne style with Art Deco details, a common design choice in courthouses of the period. While their design was generally minimalist, it includes some Art Deco decorations, such as spandrels with patterned brickwork that divide the vertically arranged windows.
