The Oregon State Capitol is the building that houses the state legislature and the offices of the governor, secretary of state, and treasurer of the U.S. state of Oregon. Built from 1936 to 1938 and expanded in 1977, it is the third building to house the Oregon state government in Salem, the state capital. Fires destroyed earlier capitols in 1855 and 1935.

Its Art Deco stripped classical design and its largely marble interior and exterior were conceived by New York architects Trowbridge & Livingston with Francis Keally. The central portion of the building, including a cupola of 166 feet (51 m), was erected at a cost of $2.5 million—partially financed by the federal government's Depression-era Public Works Administration.

The wings, which doubled the floor space of the building to about 233,750 square feet (21,716 m²), were added later for $12.5 million. The grounds outside the capitol building contain artwork, fountains, and flora, including the state tree (Douglas fir) and state flower (Oregon grape). The building was placed on the National Register of Historic Places on June 29, 1988.
