Reginald Arthur Reynolds (1905 – 16 December 1958) was a British left wing writer, poet, a Quaker and an anti-colonial activist who collaborated with M.K. Gandhi and Horace Alexander. A Quaker, he was General Secretary of the No More War Movement from 1933 to 1937. He was perhaps best known as a critic of British imperialism in India, and for his 1937 work The White Sahibs in India. For many years he was also New Statesman's weekly satirical poet. He married the left wing novelist Ethel Mannin in 1938.
