The 1951 Scottish Grand Prix was a 50 lap 100-mile (160 km) motor race held on 21 July 1951 at Winfield Airfield in Berwickshire.

Although run to Formula One regulations, the paucity of the entries led to the organisers opening up the race to other categories.

Its driver Reg Parnell was loaned local driver John Brown's HWM-Alta; Parnell started from pole position but broke a drive shaft as he left the start line.

Joe Kelly's Alta challenged and set fastest lap but retired with gearbox problems.

Murray retired with fuel pump problems and Philip Fotheringham-Parker took the lead in Duncan Hamilton's Maserati 4CL, chased home by Gillie Tyrer's BMW 328.
