John Timbs (; 17 August 1801 - 6 March 1875) was an English author and antiquary. Some of his work was published under the pseudonym of Horace Welby.
Timbs was born in 1801 in Clerkenwell, London. He was educated at a private school at Hemel Hempstead. In his sixteenth year he was apprenticed to a druggist and printer at Dorking. He had early shown literary capacity, and when nineteen began to write for the Monthly Magazine. A year later he became secretary to Sir Richard Phillips, its proprietor, and permanently adopted literature as a profession.
He was successively editor of the Mirror of Literature, the Harlequin, The Literary World, and sub-editor of the Illustrated London News. He was also founder and first editor of Year-Book of Science and Art. His published works amounted to more than one hundred and fifty volumes. In 1834 he was elected a fellow of the Society of Antiquaries of London.
Timbs died on 6 March 1875 and is buried in the churchyard of St Peter and St Paul, Edenbridge, Kent.
