An agricultural show is a public event exhibiting the equipment, animals, sports and recreation associated with agriculture and animal husbandry. The largest comprise a livestock show (a judged event or display in which breeding stock is exhibited), a trade fair, competitions, and entertainment. The work and practices of farmers, animal fanciers, cowboys, and zoologists may be displayed. The terms agricultural show and livestock show are synonymous with the North American terms county fair and state fair.

Agricultural shows are an important part of cultural life in small country towns, and a popular event in larger towns and cities. Shows range from small events in small country towns usually lasting two days, through medium-sized events of three days, to large shows, which may run for up to two weeks and combine elements of an amusement park with those of an agricultural show. Although in many countries agriculture shows are increasingly under financial pressure, many towns or areas have a show society and in some areas, several towns and villages in the area all have an annual show. Larger shows often include live entertainment and fireworks in the main arena.
