U Saw, also known as Galon U Saw, was a leading Burmese politician who served as Prime Minister of British Burma during the colonial era before the Second World War. He is also known for his role in the assassination of Burma's national hero Aung San and other independence leaders in July 1947, only months before Burma gained independence from Britain in January 1948. He was executed by hanging for this assassination.

The British colonial rule in Burma lasted from 1824 to 1948, from the successive three Anglo-Burmese wars through the creation of Burma as a province of British India to the establishment of an independently administered colony, and finally independence. The region under British control was known as British Burma, and officially known as Burma from 1886. Various portions of Burmese territories, including Arakan and Tenasserim, were annexed by the British after their victory in the First Anglo-Burmese War; Lower Burma was annexed in 1852 after the Second Anglo-Burmese War. The annexed territories were designated the minor province of British Burma in 1862.
