Sir Cyril Jackson KBE (6 February 1863 – 3 September 1924) was a British educationist, important in the development of education in Western Australia.
After leaving Oxford he took up social work at Toynbee Hall for about 10 years from 1885, and was central secretary of the Children's Country Holiday Fund.
Education in the colony had been for many years in a pitifully primitive state, but in 1890 a forward step was made by the appointment of an Englishman, J. P. Walton, as inspector of schools.
Jackson had great educational knowledge and first rate executive ability, and the foundations on which future developments could be raised were securely laid.
He also became the first Chairman of the West Guildford Roads Board (predecessor to the Town of Bassendean), the inaugural meeting of which was held in the billiard room of Jackson’s house on 12 July 1901.
