The '''Masaryk circuit''' ({{langx|cs|Masarykův okruh}}) or Masarykring, also referred to as the '''Brno Circuit''', refers to two [[motorsport]] [[race track]]s located in [[Brno]], [[Czech Republic]].
The original [[street circuit]] was made up of public roads, and at its longest measured {{convert|29.194|km|mi|abbr=on}}. The track is named after the first president of [[Czechoslovakia]], [[Tomáš Garrigue Masaryk]]. In 1949, events such as the [[Czechoslovakian Grand Prix]] attracted top teams and drivers. In 1987, the new (current) circuit was opened. The Brno Circuit is historically one of the oldest circuits, on the place were also held the most motorcycle championships in history after the [[TT Circuit Assen]].<ref>{{cite news |title=Brněnská Grand Prix je v oblibě.
