Bay to Birdwood is an annual historic motoring event in South Australia, organized by the History Trust of South Australia through the National Motor Museum. It features privately-owned vehicles and was previously divided into two events: the Bay to Birdwood Run (for pre-1956 vehicles) and the Bay to Birdwood Classic (for post-1956 vehicles), which alternated between even and odd-numbered years. Since 2020, the event has expanded to include a broader range of vintage, veteran, and classic cars, along with other road vehicles. The route begins at West Beach in coastal Adelaide and concludes at the National Motor Museum in Birdwood in the Adelaide Hills.
