The Christchurch-Campbell was an English automobile manufactured only in 1922 by J Campbell Ltd of Christchurch, Dorset (then in Hampshire), England.
An assembled car, it had a 1436 cc 10-8 hp Coventry-Simplex engine and Meadows gearbox.
At £495 for a two-seater, it was expensive and fewer than 10 were built.
