Maria Theresa Lewis (born Villiers, later Lister; 8 March 1803 – 9 November 1865) was a British writer and biographer.

[1] Lewis compiled the biography of one of her ancestors, Edward Hyde, 1st Earl of Clarendon.

Emily Eden called The Semi-Detached House in 1859, and she wrote two plays, based on fairy tales, for children to perform.

[7] Two years after the death of Sir George, Lady Lewis died from cancer in 1865 at Brasenose College, Oxford when paying a visit to the Principal.

[7] She was initially buried on 14 November 1865 in Holywell Cemetery, Oxford,[8] but the parish register of St Mary-the-Virgin Church records that “her remains were subsequently removed by the family”.
