The 2015 MSA Formula Championship was a multi-event, Formula 4 open-wheel single seater motor racing championship held across England and Scotland. The championship featured a mix of professional motor racing teams and privately funded drivers, competing in Formula 4 cars that conformed to the technical regulations for the championship. This, the inaugural season, following on from the British Formula Ford Championship, was the first year that the cars conformed to the FIA's Formula 4 regulations. Part of the TOCA tour, it formed part of the extensive program of support categories built up around the British Touring Car Championship centrepiece.
