Sydney Gedge (16 October 1829 – 6 April 1923) was a British Conservative politician and prominent lay member of the Church of England.

Born in North Runcton, Norfolk on 16 October 1829, he was the eldest son of the Rev. Sydney Gedge, and was educated at King Edward's School, Birmingham and Corpus Christi College, Cambridge.^[1] He graduated in 1854, and received a first class Moral Sciences Tripos.^[2][3] He married Augusta Herring in 1857.^[4] He was a Cambridge Apostle.
