The Old Supreme Court Chamber is the room on the ground floor of the North Wing of the United States Capitol. From 1800 to 1806, the room was the lower half of the first United States Senate chamber, and from 1810 to 1860, the courtroom for the Supreme Court of the United States.

The Old Senate Chamber is a room in the United States Capitol that was the legislative chamber of the United States Senate from 1810 to 1859 and served as the Supreme Court chamber from 1860 until 1935. It was designed in Neoclassical style and is elaborately decorated. In 1976 as part of the United States Bicentennial celebrations, it was restored to the appearance of when it served the Senate in the 1850s; it is preserved as a museum and for the Senate's use.
