1955 was the 56th season of County Championship cricket in England and there was a continuation of Surrey's complete dominance as they won a fourth successive championship title and a second consecutive Minor Counties title. England defeated South Africa 3–2.
See main article: South African cricket team in England in 1955. England won a thrilling Test series against South Africa by 3–2. England won the first two matches and then South Africa equalised the series with wins in the 3rd and 4th matches. The fifth Test was therefore the decider and England, thanks to the spin bowling of Tony Lock and Jim Laker, won by 92 runs.
