Marie Effie Wilton, Lady Bancroft (1839–1921) was an English actress and theatre manager. She appeared onstage as Marie Wilton until after her marriage in December 1867 to Squire Bancroft, when she adopted his last name. Bancroft and her husband were important in the development of Victorian era theatre through their presentation of innovative plays at the London theatres that they managed, first the Prince of Wales's Theatre and later the Haymarket Theatre. Life and career Bancroft was born at Doncaster, and as a child appeared on the stage with her parents, who were both actors. Among her early parts was that of Fleance in Macbeth (1846). She made her London début on 15 September 1856, at the Lyceum Theatre, as the boy Henri in Belphegor, playing the same night in Perdita; or, the Royal Milkmaid.

The Prince of Wales's soon became noted for its series of successful comedies by T. W. Robertson, namely: Society (1865), Ours (1866), Caste (1867), Play (1868), School (1869) and M. P. (1870). Bancroft regularly took the principal female parts in these pieces, her husband playing the leading man.
