1965 was the 66th season of County Championship cricket in England. It was the first season since the 1912 Triangular Tournament in which England played Test series against two touring sides. In the first half of a damp summer, New Zealand were the tourists, and England won all three matches. The South African side that toured in the second half of the season were much tougher opposition. South Africa won that three-match series 1–0, with two matches drawn. It was the last tour of England by a South African team until 1993. Fred Trueman's international career ended, although he did not retire from first-class cricket until the end of the 1968 season. Worcestershire won their second consecutive Championship title.
