Oliver Boyce Greene (February 14, 1915 – July 26, 1976) was an American Independent Fundamental Baptist evangelist and author.

[3] He attended North Greenville Baptist College briefly before entering full-time ministry, conducting revival meetings in tents and in churches across the eastern United States from 1939 to 1968.

On October 8, 1956, he founded The Gospel Hour, Inc. as a Christian outreach ministry using radio, personal appearances, books and audio tapes.

The radio program of his preaching was called "The Gospel Hour", which began on one station in Georgia and gradually became syndicated until the point it spanned the nation.

Taped copies of the program are still aired today on the Fundamental Broadcasting Network and several other Christian radio stations including Caribbean Radio Lighthouse in St. John's, Antigua and Barbuda and the ministry's website.
