Sir Charles Blake Cochran (25 September 1872 – 31 January 1951), professionally known as C. B. Cochran or Charles B. Cochran, was an English impresario, known for popularising the genre of revue, hitherto unfamiliar, in Britain. Apart from revue, his major theatrical successes included The Miracle in 1911, noted for its spectacular staging, The Better 'Ole (1917), This Year of Grace (1928), Bitter Sweet (1929), Cavalcade (1931) and Bless the Bride (1947). He also promoted a range of other entertainments, including professional boxing, tennis, wrestling, circus and a zoo. He published four volumes of memoirs about his life and work.
After beginning his career as an actor in the US in 1891, Cochran became a manager and press agent for theatrical and other entertainments. He returned to England in 1899 managing entertainers and eventually was producing theatre, sporting events, variety shows and revues. As a theatrical producer he was responsible for West End and some Broadway productions of shows by Noël Coward, Cole Porter, Vivian Ellis and Rogers and Hart as well as a wide range of plays by writers including Henrik Ibsen, James Barrie, Sean O'Casey, A. P. Herbert and Eugene O'Neill.
Cochran was twice bankrupt – some of his productions were unsustainably lavish and expensive – but by the end of his career he had been honoured with a knighthood in Britain and the Legion of Honour in France.
