Truck Festival is an annual music festival in Oxfordshire, England. It was started in 1998 by the Bennett family (including the brothers Robin and Joe of the band Goldrush), who decided that mainstream festivals such as Glastonbury had become too commercial and predictable. It is held in July at Hill Farm in Steventon, near Abingdon. The festival also gave birth to the Truck Records label in 1999.

The main stage is constructed from three large flatbed trucks, and a common misperception is that this is where the name of the festival comes from. However in 2007 Robin Bennett wrote on the official Truck website: "Contrary to popular belief, the name Truck actually came from a compilation CD I picked up, 'Ten Trucking Greats', the soundtrack of the movie Convoy."

Truck has grown somewhat since its inception, but with an annual attendance of around 5,000 it is dwarfed by the likes of Glastonbury (around 150,000 people) and Reading/Leeds. Part of Truck's appeal for fans is that it can be viewed as a microcosm of these larger festivals, with a similar layout and facilities but on a more manageable scale. Due to a variety of factors, chiefly the layout of Hill Farm, it is highly unlikely that Truck has any potential for significant growth in the near future.

Hill Farm remains very much a working farm, shutting down only temporarily to allow the festival to take place each year. One of Truck's six stages is the so-called "Barn That Cannot Be Named" — a cow-shed with a stage set up at one end — which, despite the rich smell of manure, remains an ever-popular place to watch bands at the festival. The Barn mainly plays host to metal, emo, hardcore and punk acts during the day, then on Saturday evening turns into a drum and bass arena, returning to its rock incarnation on Sunday.

Other stages include Trailer Park, a marquee in the main arena which features the more esoteric indie bands during the day, and breakbeats on Saturday night; the Lounge, a smaller marquee which used to specialise in more ambient and chilled performances during the day, and trance during the night but now plays host to a number of local, national, and international bands and DJ's; the Market tent, which is set in the market area a short walk from the main field and features mainly folk-oriented music, becoming a retro disco/karaoke venue on Saturday night; and the Theatre/Fringe tent, which hosts non-musical acts such as theatrical performances, stand-up comedy, performance art and spoken-word performers.

The festival prides itself on its family atmosphere, with all of the site services being provided by local groups: the food stall is run by the local Rotary Club, and ice cream is sold by the local vicar. All profits from the festival go to charity.

A compilation album is released each year on Truck Records to coincide with the festival, featuring tracks (mainly studio recordings) from various bands playing at the festival.
