Ethel Agnes Mary Moorhead (28 August 1869 – 4 March 1955) was a British suffragette and painter and was the first suffragette in Scotland to be forcibly-fed.

She was also a patron of This Quarter, a journal published by Ernest Walsh. The journal featured writers such as Ernest Hemingway, James Joyce and Ezra Pound.

Moorhead was born on 28 August 1869 in Fisher Street, Maidstone, Kent. She was one of six children of Brigadier Surgeon George Alexander Moorhead, an army surgeon of Irish Catholic birth, and his wife, Margaret Humphreys (1833–1902), an Irish woman of French-Huguenot ancestry, whom he had married in India, at Madras Roman Catholic Cathedral on 9 September 1864.

Her maternal grandfather was Captain John Goulin Humphreys, a Napoleonic Wars veteran and in an earlier generation one of her mother's family (Pierre Goulin) fought in the 1690 Battle of the Boyne.

Her older sister Alice Moorhead (1868–1910) was a pioneer of female medicine, trained as a surgeon and physician, and four of her brothers were doctors, as were several male members of her father's family.

Her father was posted with the Berkshire Regiment to Afghanistan as army surgeon in 1870, and she would have seen little of him in her early years, from his time in India in the post-mutiny years to being promoted to Surgeon-Major when Moorhead was just four years old. The family lived in Shoeburyness in Kent and then he was posted to Port Louis, Mauritius and retired as Brigadier-Surgeon in 1880, and they moved to Galway, where the children were schooled. When her brothers George Oliver and Arthur and sister Alice were studying medicine in Edinburgh, from 1888 to 1894, the family were at 20 Windsor Street, Edinburgh. Then the family were in St. Helier, Jersey before going to Glasgow, where another brother, Rupert, studied medicine, before her father settled at 20 Magdalen Yard Road, Dundee from 1900 and so in 1902 lived closer to Alice and her newly created Dundee Women's Hospital. The family then moved temporarily to Pitalpin House, Lochee and in 1907 moved into the newly built 'The Wiesha' at Hazel Drive, Dundee, where Moorhead was able to have a studio.

After training as an artist, when she was 29, in Paris under Mucha and in Whistler's studio, the Atelier Carmen, between October 1898 and April 1901, with fellow Dundee painter, Janet Oliphant, Moorhead returned to Dundee and set up a portrait studio with Oliphant where she worked for fifteen years, in The Arcade, 4 King Street. Both joined the Dundee Graphic Art Association, Oliphant as an associate, Moorhead as ordinary member up to 1909. Moorhead's first exhibition was a landscape and six other pictures, in the Centennial Exhibition in 1901, with the local press, including the Dundee Advertiser praising her work as among the 'gems of the collection from an artistic point of view.' Her mother died in 1902, and she took over the care for her father from 1908 (after Alice married, with Ethel as a witness) and she often used her father as a model, one titled Brigade Surgeon G. A. Moorhead was described as 'in the way of portraiture.. nothing finer.. a triumph of art' in the Courier, and Moorhead knowing the sitter made a difference, said the Evening Telegraph. The Celtic Annual described her as a 'most refined and distinguished artist' and at her last exhibition with the Dundee Graphic Artists, the pricing for paintings increased.

Her sister Alice died in childbirth in 1910, and her father then died in 1911; both were buried with her mother in Dundee's Western Cemetery.
