Ogden Codman Jr. was an American architect and interior decorator in the Beaux-Arts styles, and co-author with Edith Wharton of The Decoration of Houses (1897), which became a standard in American interior design.

The Codman Carriage House and Stable is a historic building located at 1415 22nd Street NW in the Dupont Circle neighborhood of Washington, D.C. The industrial building was constructed in 1907 as a carriage house and stable for socialite and art collector Martha Catherine Codman, who lived a few blocks north in her home, later known as the Codman–Davis House. She commissioned her cousin, Ogden Codman Jr., an architect and prominent interior decorator who also designed her home. He designed it in a Second Empire style.
