The A423 road is a primary A road in England in two sections. The main section leads from central Banbury to the A45 near Coventry. It starts in Banbury town centre as Southam Road and goes through the Southam Road Industrial Estate, then just north of Banbury it crosses over the M40, from there it passes close to several Warwickshire villages until it becomes part of the Southam by-pass, it then goes through Long Itchington and Marton before merging with the A45 near Ryton.

The other section of the A423 is part of the Oxford Ring Road between the A34 Hinksey Hill interchange and the A4142/A4074 Heyford Hill roundabout, a distance of 1.4 miles (2.3 km)

Its original route when first classified in 1922 was from Tamworth in Staffordshire to Oxford. In the 1930s the route was extended from Oxford to the A4 near Maidenhead in Berkshire, over parts of the former routes of the A42 and A415. A curious feature of the route was a 3-mile (4.8 km) gap between Benson, Oxfordshire and a point 1.2 miles (1.9 km) north west of Nuffield, which resulted from the construction of RAF Benson across the line of the road. The detour though Crowmarsh Gifford was designated the B479 and A4130 rather than A423.
