The F. S. Baird Machine Shop, located at 632 East Adams Street between North 6th and North 7th Streets in downtown Phoenix, Arizona, is part of Heritage Square, a collection of historic buildings dating from the city's earliest days. It was built in 1928 by Kathryn Baird, who opened a machine shop there with her son Arthur in 1929. After Arthur left the business in 1931, George W. Wilson operated a machine shop business in the building until 1933, followed by various other owners until 1941. Between 1947 and 1964, a variety of industrial shops occupied the space. In 1978, the city of Phoenix purchased the vacant building to add it to Heritage Square, which is anchored by the nearby Rosson House. It is currently the site of a pizza restaurant.
