The Left Book Club was a publishing group that exerted a strong left-wing influence in Great Britain from 1936 to 1948. Pioneered by Victor Gollancz, it offered a monthly book choice, for sale to members only, as well as a newsletter that acquired the status of a major political magazine. It also held an annual rally. Membership peaked at 57,000, but after the Soviet-Nazi non-aggression pact of 1939, it disowned its large Communist element, and subsequent years of paper-rationing, during and after the war, led to further decline.

Despite its pro-Communist line, the Club's socialist propaganda and education probably ultimately strengthened the Labour Party and contributed to its victory in the postwar election. The club supplied a book chosen every month by Gollancz and his panel (Harold Laski and John Strachey) to its members, many of whom took part in one of the 1,500 Left Discussion Groups scattered around the country. The books and pamphlets with their distinctive covers—orange for paperback (1936–1938) and red for hardback (1938–1948) editions—bore the legend "NOT FOR SALE TO THE PUBLIC" and sold for 2s 6d to members. Many titles were available for sale only in the LBC edition, with monthly 'choices' received by all members; there were also reprints of current socialist and 'progressive' classics for members to buy.
