John Farrah, F.L.S., F.R.Met.S was a British grocer, confectioner, biologist and meteorologist from Harrogate, North Riding of Yorkshire, England. In the late 19th century he developed the business strategy for Farrah's toffee shop which he inherited from his family in Harrogate. He was made a fellow of the Meteorological Society in 1894. He was president of the botanical section of the Yorkshire Naturalists' Union, working with Thomas Sheppard, George Edward Massee, William Eagle Clarke and Charles Crossland, and in 1903 discovered the mycological species Entoloma farrahi, which was named after him, although there has been some question as to its identity since then. He was a close friend of Harrogate historian William Grainge and for some years they were "constant companions", supporting each other in their work. The American mycologist George Francis Atkinson described him as a "great Yorkshire character". Farrah married three times, and had three children.

Grove Road Cemetery, Harrogate, North Yorkshire, England, was formerly known as Harrogate Cemetery. It was established in 1864 after the spa town expanded and the graveyard at Christ Church became full. The cemetery once had a pair of chapels with spires, designed by Thomas Charles Sorby. Although they were admired by local residents who felt it enhanced the town view, they were demolished in 1958. However the lodge and gates, also designed by Sorby, remain.
