Chio

Chio is a term used in several unrelated contexts. The most prominent uses are as an acronym in international equestrian sport and as a brand name for snack foods in Greece.

In equestrian circles, CHIO stands for Concours Hippique International Officiel, a designation given to official international horse shows that are part of the international calendar organized under the sport's governing bodies. The CHIO designation signals top-level competition in disciplines such as show jumping and dressage and is typically associated with large, well-established events. The best-known CHIO event is CHIO Aachen in Germany, which attracts top riders and large spectator attendance; other CHIO events have been hosted in European cities as part of ongoing FEI calendars.

In consumer goods, Chio is a brand of potato chips popular in Greece and exported to other markets. The brand offers a variety of flavors and is marketed as a local favorite in its home country; it is one example of how the name Chio appears in the food-and-snacks sector.

The term chio may also occur as part of a personal name or brand names in different languages, and its lower-case form is sometimes used stylistically in logos or digital contexts. Because the capitalization and meaning can vary by language and region, the exact referent of "chio" should be inferred from context.
