Wariyapola Sri Sumangala (Sinhala:වාරියපොල ශ්රි සුමංගල) was a Buddhist monk who lived in the early 19th century in Sri Lanka (then known as Sinhale). He was an Anunayaka of the Asgiriya Chapter. Sri Sumangala is known for taking down the Union Jack and re-hoisting the Sinhalese lion flag, before the convention that handed over control of the island to the British in 1815. Later during the rebellion of 1818, he removed the Tooth Relic of the Buddha from the Temple of the Tooth, and handed it over to the leaders of the rebellion. He was arrested and convicted for treason the same year.
