The 2023 Michelin Ginetta Junior Championship was a multi-event, one make motor racing championship held across England. The championship included a mix of professional teams and privately funded drivers, aged between 14 and 17, competing in Ginetta G40s that conformed to the technical regulations for the championship.
The calendar was unveiled on 21 September 2022, and ran alongside the British GT Championship for the first time, as was previously run as part of the TOCA package.
