Lieutenant-General Sir Michael Frederic Rimington, (23 May 1858 – 19 December 1928) was a British Army officer who commanded cavalry forces in the Second Boer War and First World War. After early service with the 6th (Inniskilling) Dragoons, "Mike" Rimington was given command of an irregular cavalry force in South Africa, known as "Rimington's Guides". He commanded them for a year before taking command of his regular regiment, and later a cavalry brigade. In 1914, with the outbreak of the First World War, he commanded the 1st Indian Cavalry Division and then the Indian Cavalry Corps on the Western Front, before retiring to home-service duties in 1916. He had one son, Reginald, who followed his father into the 6th Dragoons; he rose to command an armoured brigade in 1941, and was killed in North Africa.
