Red Butte Garden and Arboretum is a botanical garden and arboretum operated by the University of Utah, in the foothills of the Wasatch Range in Salt Lake City, Utah, USA. It is open year-round to the public. Red Butte Garden contains 18 acres (0.073 km2) of botanical gardens and several miles of hiking trails through native vegetation.
The garden began in 1930, when Dr. Walter P. Cottam, co-founder of The Nature Conservancy and chairman of the Botany Department at the University of Utah, began using campus land for plant research. In 1961, the Utah legislature designated the University's campus landscape as the State Arboretum. In 1983, the University dedicated 100 acres (0.40 km2) at the mouth of Red Butte Canyon for a regional botanical garden.
Red Butte Garden hosts a series of popular summer music concerts as well as floral, sculpture, and other art exhibits. The garden also offers many nature-related classes and events.
