John Russell, Viscount Amberley (10 December 1842 – 9 January 1876), was a British politician and writer. He was the eldest son of John Russell, who twice served as Prime Minister of the United Kingdom, and father of the philosopher Bertrand Russell. Amberley is known for his unorthodox views on religion and for his active support of birth control and women's suffrage, which contributed to the end of his short career as Liberal Member of Parliament.
