Charles Oswald Miles (30 May 1850 – 11 August 1898) was an Anglican priest.
Miles was educated at Marlborough College and Trinity College, Oxford where he took an MA in Classics in 1875. He also attended Cuddesdon College in their fourth term of 1873 and terms one to three of 1874 where he trained for the priesthood.
Miles was ordained deacon on 20 September 1874 by John Fielder Mackarness, Bishop of Oxford, and was curate of Banbury (1874–1876). He was ordained a priest, also by the Bishop of Oxford, on 19 September 1875 and became curate of Buckingham (1876–1877). He then sought opportunities abroad and sailed for South Africa in 1877.
Bishop Allan Becher Webb established the St Cyprian's Theological College in a building in St George's Street, Bloemfontein, in 1876, in the hopes of addressing some the needs of the still new, isolated, poor and sparsely populated Diocese of Bloemfontein. It opened in 1877, with Bishop Webb himself, Archdeacon Davis Croghan, the Revd K. Champernowne, and the Revd William Thomas Gaul as lecturers. Miles was recruited due to his Cuddesden connections to serve here as Theological Tutor and was Warden of the College from 1877–1882. "Native" students were tutored by the Revd William Crisp. The College was not, however, a success and served latterly only as a boarding house until that closed in 1883.
Whilst at the college, Miles also served as rector of St Cyprian's Church in Kimberley from 1881–1882.
Miles also served from 1880 to 1882 as a canon and the chancellor of the Anglican Diocese of the Free State under Bishop Webb.
