2020 F4 British Championship

The 2020 F4 British Championship certified by FIA – powered by Ford EcoBoost was a multi-event, Formula 4 open-wheel single seater motor racing championship held across United Kingdom. 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 sixth season, following on from the British Formula Ford Championship, was also the sixth 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 BTCC centrepiece.

The season commenced on 1 August at Donington Park and concluded on 15 November at the Brands Hatch Indy Circuit, after twenty-six races held at nine meetings, all in support of the 2020 British Touring Car Championship.

Luke Browning was crowned champion at Brands Hatch, finishing four points ahead of his championship rival Zak O'Sullivan.
