Emerald Downs, Horse racing track in Auburn, United States

Emerald Downs is a Thoroughbred racetrack in Auburn, Washington, half a mile east of Highway 167. Its grandstand, designed by EwingCole, has a stepped facade with teal panels, grey and white sections with rows of square windows, and a wide grey band carrying the gold lettering "EMERALD DOWNS" above green-and-white striped awnings. The one-mile oval has no turf course, and the tote board stands in the infield.

The track opened in 1996 on land previously occupied by Longacres Racetrack, which had operated for decades before closing. The Muckleshoot Indian Tribe bought the property in 2002 and took over full operations in 2015.

Emerald Downs takes its name from Seattle, the Emerald City. The Muckleshoot Indian Tribe bought the land in 2002 for about $70 million and formed Emerald Downs Racing LLC in 2015. Each Father's Day weekend the track hosts Indian Relay Racing, a team horse-racing event.

Live Thoroughbred racing runs in spring and summer, with races Friday through Sunday during the summer months. The grandstand has general admission seating on track level, including a grassy park area with free children's activities on weekends when weather permits. Box and reserved seats are on the third floor and in the fifth-floor indoor clubhouse, and parimutuel windows are on each floor.

The track's signature race, the Longacres Mile, was announced in June 1935 by Longacres founder Joe Gottstein, who thought the mile distance was overlooked. Its first purse of $10,000 made it the richest one-mile race in the country for over 40 years. The 75th running, on August 22, 2010, was won by favorite Noosa Beach.
