Edgar Sanderson (1838–1907) was an English cleric, schoolteacher and historical writer.
Born at Nottingham on 25 January 1838, he was son of Edgar Sanderson by his wife Eliza Rumsey; his father owned a lace-factory in Nottingham, and later kept schools at Stockwell and Streatham Common. The younger Sanderson was educated at the City of London School and at Clare College, Cambridge from 1856, where he won a scholarship. He graduated B.A. in 1860, proceeding M.A. in 1866.
After holding a mastership at King's Lynn grammar school, Sanderson was ordained deacon in 1862 and priest in 1863. At first curate of St. Dunstan's, Stepney, while master of Stepney grammar school, he held successively curacies at Burcombe-cum-Broadway in Dorset (with a mastership at Weymouth school), and at Chieveley, Berkshire. From 1870 to 1873 Sanderson was headmaster of Stockwell grammar school; from 1873 to 1877 of Macclesfield grammar school; and from 1877 to 1881 of Huntingdon grammar school.
Subsequently Sanderson lived at Streatham Common, writing educational manuals and popular historical works. He died at 23 Barrow Road, Streatham Common, on 31 December 1907, and was buried at Norwood cemetery.
