James Elmes (15 October 1782, London – 2 April 1862, Greenwich) was an English architect, civil engineer, and writer on the arts.
Elmes was educated at Merchant Taylors' School, and, after studying building under his father, and architecture under George Gibson, became a student at the Royal Academy, where he gained the silver medal in 1804. He designed a large number of buildings in London, and was surveyor and civil engineer to the Port of London, but is best known as a writer on the arts. He exhibited at the Royal Academy between 1801 and 1842.  He was vice-president of the London Architectural Society from its foundation in 1806.
In 1813-4 he restored the top part of the spire of Chichester Cathedral, reconstructing the pendulum device incorporated into it by Sir Christopher Wren to counteract the effects of strong winds. Elmes described the contraption in his biography of Wren, calling it "one of the most ingenious and appropriate of its great inventor's applications."
He was the founder and editor of the Annals of the Fine Arts, a quarterly magazine published between 1816 and 1820. The content of the periodical was greatly influenced by the views of the historical painter Benjamin Robert Haydon, with whom Elmes had become friends while both were still students at the Royal Academy. Elmes claimed to have written the first review of Haydon's work ever published, in the Monthly Magazine in 1806. He also edited the Magazine of the Fine Arts and Monthly Review from 1821.
Elmes resigned from his post with the Port of London in 1848, due to a loss of sight, from which he later partially recovered.
His buildings included:
- St John the Evangelist's Church, Chichester (1812–13) built in the Classical-style as an Anglican proprietary chapel. The Grade I-listed building is now redundant and in the care of the Churches Conservation Trust.
- The New House of Correction, Bedford (1819). Sited on the main road from Bedford to Kettering, it was arranged on the panopticon system. The building was demolished 1851.
