Violet Rosa Markham CH (October 1872 – 2 February 1959) was a writer, social reformer, campaigner against women's suffrage and administrator.

Actively involved in community and welfare work, she held a number of public positions, including in educational administration, and social assistance and poverty relief bodies.

When a friend of her late father died in 1901, Violet inherited enough money to live an independent life and devote her wealth to causes she supported, as well as to buy her own house in London.

In 1917 she was made deputy director of the women's section of the National Service League, and was one of the first recipients of the Order of the Companions of Honour.

She was on the appeal tribunal of the Defence of the Realm Regulations, and in 1942, she was asked to produce a report on allegations of immorality in the women's services.

Markham told the audience that the views of the women's suffrage movement "fly in the face of hard facts and natural law.

"[6] She went on to say that, "We believe that men and women are different – not similar – beings, with talents that are complementary, not identical, and that they therefore ought to have different shares in the management of the State, that they severally compose.

She accompanied her husband to Cologne, when he was stationed there as chief demobilisation officer for the British Army of the Rhine, following the First World War.

She wrote several books, including Paxton and the Bachelor Duke, a biography of her grandfather (1935), her autobiography, Return Passage (1953), and Friendship's Harvest (1956).
