Athletics is an exclusive collection of sporting events that involve competitive running, jumping, throwing, and walking. The most common types of athletics competitions are track and field, road running, cross country running, and race walking. The simplicity of the competitions, and the lack of a need for expensive equipment, makes athletics one of the most commonly competed sports in the world.

Organised athletics are traced back to the Ancient Olympic Games from 776 BC, and most modern events are conducted by the member clubs of the International Association of Athletics Federations. The athletics meeting forms the backbone of the modern Summer Olympics, and other leading international meetings include the IAAF World Championships and World Indoor Championships, and athletes with a physical disability compete at the Summer Paralympics and the IPC Athletics World Championships.

The word athletics is derived from the Greek word "athlos" (ἄθλος), meaning "contest" or "task." Initially, the term was used to describe athletic contests in general – i.e. sporting competition based primarily on human physical feats. In the 19th century in Europe, the term athletics acquired a more narrow definition and came to describe sports involving competitive running, walking, jumping and throwing. This definition continues to be the most prominent one in the United Kingdom and most of the areas of the former British Empire. Furthermore, foreign words in many Germanic and Romance languages which are related to the term athletics also have a similar meaning.
