Carl Gustav Boberg (16 August 1859 – 7 January 1940) was a Swedish poet and elected official, best known for writing the Swedish language poem of "O Store Gud" (O great God) from which the English language hymn "How Great Thou Art" is derived.
Born in Mönsterås, Kalmar County in Småland, Boberg was a carpenter’s son, worked briefly as a sailor, and served as a lay minister in the Mission Covenant Church of Sweden. He was the editor of a weekly Christian newspaper, Sanningsvittnet (Witness of the Truth), from 1890 until 1916. Boberg served in the Riksdag for 20 years from 1912 to 1931. He published more than 60 poems, hymns, and gospel songs, including a collaboration with Swedish hymnist Lina Sandell.
