Tubal Uriah "Buzz" Butler (1897-1977), was a Grenadian-born preacher and labour leader in Trinidad and Tobago. He is best known for leading a series of labour roits between June 19 and July 6, 1937 and for forming a series of personalist political parties (the British Empire Citizens' and Workers' Home Rule Party, the Butler Home Rule Party and finally the Butler Party) that focused its platform on the improvement of the working class.

Following the riots Butler was imprisoned from September 9, 1937 to May 1939. With the outbreak of World War II in September, 1939, Butler was re-arrested and detained for the duration of the war.

Butler is looked upon as the founding father of the Oilfields Workers' Trade Union (OWTU) and is honoured with a statue in Fyzabad, the town in which the strikes began. He was awarded the Trinity Cross, the nation's highest honour, in 1970.
