The 1977 British Formula Three season was the 27th season of the British Formula Three season. Derek Daly took the B.A.R.C. BP Super Visco British Formula 3 Championship, while Stephen South took the B.R.D.C. Vandervell British Formula 3 Championship. The success of the European Championship, now in its third season, stole some of the limelight from the British championships in 1977 and the continuing divide between the BP-sponsored BARC title and the Vandervell-sponsored BRDC title cannot have helped.
