Henry Garland Dupré (July 28, 1873 - February 21, 1924)[1] was from 1910 to 1924 a Democratic member of the United States House of Representatives for Louisiana's 2nd congressional district, based about New Orleans, Louisiana.
Born in Opelousas in St. Landry Parish in south Louisiana, Dupré attended public schools and graduated in 1892 from Tulane University in New Orleans and thereafter the Tulane University Law School. In 1895, he was admitted to the bar and began his law practice in New Orleans.
He served as assistant city attorney of New Orleans from 1900 to 1910. During that same period, he was the District 14 member of the Louisiana House of Representatives for Orleans Parish. He was House Speaker from 1908 to 1910.[2] In 1908, he chaired the Louisiana Democratic State Convention.
Dupré was elected to the Sixty-first Congress to fill the vacancy caused by the death of Samuel Louis Gilmore. He was reelected to the Sixty-second and the six succeeding Congresses and served from November 8, 1910, until his death in Washington, D.C., on February 21, 1924. He is interred at the Catholic Cemetery in his native Opelousas.
