The name is first recorded in 848 as Grenan forda. It is formed from the Old English 'grene' and 'ford' and means 'place at the green ford'. Greenford was known as Great Greenford in order to distinguish it from Little Greenford, which is now known as Perivale. The affixes 'Magna' and 'Parva' have also been used to denote the difference.

Greenford is considered to be birthplace of the modern organic chemical industry, as it was at William Perkin's chemical factory in North Greenford, by the Grand Union Canal, that the world's first aniline dye was discovered in March 1856. Perkin called his amazing discovery 'mauveine'. Today there is a blue plaque marking the spot in Oldfield Lane North, just south of the Black Horse public house. Until 2013/14, Greenford was the home to the Hovis factory. The former Rockware glassworks on the canal is commemorated by Rockware Avenue. Greenford formed part of Greenford Urban District from 1894 to 1926 and was then absorbed by the Municipal Borough of Ealing.

Five hundred yards north east from William Perkin's dye factory was a triangular field in which he kept horses. On this ground was built the Oldfield Tavern public house, which became a popular venue for a rock group called the Detours, who met a drummer there called Keith Moon. On Thursday 20 February 1964 they were introduced to the audience of the Oldfield Tavern as the Who. (The tavern has not survived, however, and has since been replaced by a small block of flats and a Texaco petrol station). Andy Locke, Dave Kerr-Clemenson and Wal Scott were all in Edison Lighthouse, and with chart-topping Love Grows all came from Greenford.
