Lieutenant-Colonel Edward Marten Dunne (27 August 1864 – 23 February 1944) was a British army officer and Liberal politician.
He was the third son of Thomas Dunne of Gatley Park and Bircher Hall, Herefordshire and his wife, Harriet (née Russell). His maternal grandfather was General Sir Edward Lechmere Graves Russell of Ashford Hall, Ludlow, Shropshire.
Following education at Wellington College and the Royal Military College Sandhurst, he received a commission as an officer in the Border Regiment in 1884. He subsequently entered the Staff College, passing out of the institution in 1891. In 1896 his father died, and he resigned his commission.
In 1899 he married Grace Daphne Rendel, daughter of Lord Rendel, former Liberal MP for Montgomeryshire. On the outbreak of the Second Boer War in the same year, he volunteered to return to the army, becoming brigade major at Aldershot. Following the war the couple moved to Gatley Park, an estate adjoining Wigmore Castle.
In 1905 Dunne unsuccessfully contested a by-election at Kingswinford for the Liberals. In the following year a general election was held, and he was elected to serve as member of parliament for Walsall. He was only an MP for one term: at the next general election in January 1910 he was defeated by his Conservative opponent. He was chosen as Liberal candidate for the Melton Division of Leicestershire at the next election in December, but was not elected.
