Robert Woodward Barnwell (December 27, 1849 – July 24, 1902) was the third bishop of the Diocese of Alabama in The Episcopal Church, serving only two years.
[2] While there, he was a member of the Fraternity of Delta Psi (St. Anthony Hall).
He served in St George's Church in Griffin, Georgia, between 1873 and 1876.
In 1876, he transferred to Demopolis, Alabama, as rector of Trinity Church, while in 1880, he became rector of St Paul's Church in Selma, Alabama.
However, prior to his consecration, the diocesan bishop of Alabama Richard Hooker Wilmer died and hence Barnwell was instead consecrated as the third diocesan Bishop of Alabama on July 25, 1900, in St Paul's Church, Selma by the Bishop of Mississippi Hugh Miller Thompson.
