The Townsville 500 (formally known as the NTI Townsville 500) is an annual motor racing event for Supercars, held on the Reid Park Street Circuit in Townsville, Queensland, Australia. The event has been held since 2009.
The event was known as the Townsville 400, based on a 400 kilometre format, in ten of the first eleven years of the event. In 2021, the event returned to the 500 kilometre format first used in 2014, while in both 2020 and 2021, two Townsville events were held under the Townsville SuperSprint banner due to calendar changes and shorter races caused by the COVID-19 pandemic.
