Carl Gustaf Grimberg (22 September 1875 in Gothenburg, Sweden – 11 June 1941 in Djursholm) was a Swedish historian. His parents were Joel Grimberg and Charlotta (née Andersson); in 1919, he married Eva Carlsdotter Sparre (1895–1982). Grimberg completed his PhD in 1903 and then took a teaching job. In 1905 he began to write a school textbook, focussing on the history of Sweden and its diplomatic relations with Prussia, Denmark and other countries. In 1908 he left his teaching job to concentrate fully on his writing. Grimberg's most famous work is his history of Sweden, Svenska folkets underbara öden (1913-1924); in 1926 Grimberg began to publish his history of the world, Världshistoria, but he did not finish it before his death.
