Sydney Black (25 July 1860 - 22 October 1903) was an evangelical minister and educationist.
He was the oldest surviving son of Robert Black and Sarah Ann Wallis, of Twynholm, Kirkcudbrightshire, Scotland. The couple moved to Knightsbridge in London where Robert carried on business as a draper. He was a member of the Church of Christ, a Protestant sect, and he helped establish Chapel Street Chapel, Chelsea, becoming an elder of the church on his retirement from business in 1875.
Sydney was educated at the Western Grammar School, Brompton and the Nonconformist Grammar School, Bishop's Stortford. At the age of 15 he decided to become a minister and preached his first sermon at the age of 17. He preached in various parts of England before returning to London in 1888. He held services in the Town Hall, Chelsea, until he entered the University of Oxford in 1889. He subsequently travelled to Australia, New Zealand and the United States.
In 1893 he returned to London and established a new chapel "Twynholm House" at Fulham Cross.
In 1899 he was elected to the Fulham Board of Guardians and in 1900 was elected to the London School Board as a Progressive Party member representing the Chelsea Division. Early in 1903 his health failed, and he was forced to resign from the board.
He died in 1903 aged 43, and was buried in Fulham Cemetery.
