Anagarika Dharmapala (17 September 1864 – 29 April 1933) was a Sri Lankan Buddhist revivalist and writer. He was one of the founding contributors of non-violent Sinhalese Buddhist nationalism and Buddhism. He was also a pioneer in the revival of Buddhism in India after it had been virtually extinct there for several centuries, and he was the first Buddhist in modern times to preach the Dharma in three continents: Asia, North America, and Europe. Along with Henry Steel Olcott and Helena Blavatsky, the creators of the Theosophical Society, he was a major reformer and revivalist of Ceylonese Buddhism and an important figure in its western transmission. At the latter stages of his life, he entered the order of Buddhist monks as Venerable Sri Devamitta Dharmapala.
