Sydney Showground Speedway, originally known as the Speedway Royal and later the Speedway Royale but often referred to as just The Royale or The Showground, was a motorcycle speedway track, which was located at the old Sydney Showground and used from 1926 until 1996.

Motorcycle speedway, usually referred to simply as speedway, is a motorcycle sport involving four and sometimes up to six riders competing over four anti-clockwise laps of an oval circuit. The motorcycles are specialist machines that use only one gear and have no brakes. Racing takes place on a flat oval track usually consisting of dirt, loosely packed shale, or crushed rock. Competitors use this surface to slide their machines sideways, powersliding or broadsiding into the bends. On the straight sections of the track, the motorcycles reach speeds of up to 70 miles per hour (110 km/h).
