Hertfordshire Rangers F.C. were a 19th-century English amateur football team based in Watford, Hertfordshire. They competed in the FA Cup and had two players represent England in international matches.
The club received FA recognition in 1866, and were formed at some point before that. Rangers featured in the FA Cup between 1875 and 1881, making them the dominant side in Hertfordshire. One reliable source states that they were founded in 1865.
Their team were largely composed of players from Cambridge University students, as the university did not have a team at the time, and schools at Aldenham and Elstree. When the club folded in December 1882, it was because they were unable to replace players who had left the schools for university.
A club bearing the same name was formed in 2001.
The club occupied three grounds during their history, all of which were close to Watford Junction and the Malden Hotel, their social headquarters. One of these grounds was a meadow on Langley Road, Watford.
