The Perth SpeedDome is a velodrome in Midvale, Western Australia, Australia. It is Western Australia's only indoor velodrome. It was designed by German architect Ralph Schürmann and constructed under the supervision of English velodrome specialist Ron Webb. The SpeedDome was opened in November 1989, replacing the Lake Monger Velodrome, an old outdoor concrete velodrome in Mount Hawthorn. The SpeedDome hosted the 1997 UCI Track Cycling World Championships.
