Granville Gaylord Bennett (November 28, 1882 – October 3, 1975) was the second Bishop of Duluth and the eighth Bishop of Rhode Island in the Episcopal Church in the United States of America.

Bennett was born in Deadwood, South Dakota on November 28, 1882, the son of Judge Granville Gaylord Bennett, an American lawyer who served as a justice of the Supreme Court for the Dakota Territory and as a delegate to the United States House of Representatives, and Mary Ann Bennett née Dawson.

He had two sisters, Estelline Rea Bennett (1868 - 1948), author of OLD DEADWOOD DAYS, and Helen Marie Bennett (1872 - 1962), an American journalist, businesswoman, and writer who organized the four women's world's fairs of the 1920s.

An older brother, Robert Dawson Bennett (1878 - 1892) was killed in a tragic hunting accident at age 14.

He was consecrated in November of that same year by Presiding Bishop Daniel S. Tuttle.
