The Devon County Show is an agricultural show held annually at the Westpoint Arena and Showground in Clyst St Mary near Exeter.  It is one of a number of county shows in the United Kingdom. The show is a celebration of rural life in Devon, and features country and livestock competitions, a grand parade, equine events, local food and local drink, traditional entertainment and rural crafts.

The show goes back to 1872, when the Devon County Agricultural Association was formed to undertake promotion of the Devon County Show. It has been held annually ever since, except for breaks during the two World Wars from 1940 to 1946 and 1915 to 1919, and eleven occasions between 1890 and 1958, when it was held in conjunction with Bath and West Show or the Royal Show when these were held in Devon. The show was first held at Victoria Park, Mount Radford and then at various sites around the county until 1956, when it moved to its first permanent site at Whipton Showground, Exeter. The show moved to its present site at the Westpoint Arena in 1990.
