Mary Charlotte Moore (3 July 1861 – 6 April 1931), Lady Wyndham, was an English actress and theatrical manager. She was known for her appearances in comedies alongside the actor-manager Charles Wyndham between 1885 and his retirement in 1913. Over these three decades they acted mainly in contemporary plays, many written for them by authors including Henry Arthur Jones and Hubert Henry Davies, but also appeared in classic comedies together. She continued to act on stage until 1919. She was married to the playwright James Albery from 1879 to 1889, and after his death her relationship with Wyndham eventually became romantic. After the death of Wyndham's estranged wife in 1916, he and Moore married.
