George Manville Fenn (3 January 1831 in Pimlico – 26 August 1909 in Isleworth) was a prolific English novelist, journalist, editor and educationalist.

After studying at Battersea Training College for teachers (1851–1854), he became the master of a national school at Alford, Lincolnshire.

Fenn later became a printer, editor and publisher of some short-lived periodicals, before attracting the attention of Charles Dickens and others with a sketch for All the Year Round in 1864.

Fenn authored many historical fiction novels, including Crown and Sceptre: A West-Country Story (1889) about the English Civil War, Ned Ledger (1899), focusing on naval combat during War of the Austrian Succession, The King's Sons (1901) about King Alfred, and Marcus, the Young Centurion (1904), about Julius Caesar.

[3] Fenn and his family lived at Syon Lodge, Isleworth, Middlesex, where he built up a library of 25,000 volumes and took up telescope making.
