A sports club or sporting club, sometimes an athletics club or sports society or sports association, is a group of people formed for the purpose of playing sports.

Sports clubs range from organisations whose members play together, unpaid, and may play other similar clubs on occasion, watched mostly by family and friends, to large commercial organisations with professional players which have teams that regularly compete against those of other clubs and sometimes attract very large crowds of paying spectators. Clubs may be dedicated to a single sport or to several (multi-sport clubs).

The term "athletics club" is sometimes used for a general sports club, rather than one dedicated to athletics proper.

Friedrich Ludwig Jahn's Turner movement, first realised at Volkspark Hasenheide in Berlin in 1811, was the origin of the modern sports clubs.

Larger sports clubs are characterized by having professional and amateur departments in various sports such as bike polo, football, basketball, futsal, cricket, volleyball, handball, rink hockey, bowling, water polo, rugby, track and field athletics, boxing, baseball, cycling, tennis, rowing, gymnastics, and others, including less traditional sports such as airsoft, billiards, e-sports, orienteering, paintball, or roller derby. The teams and athletes belonging to a sports club may compete in several different leagues, championships and tournaments wearing the same club colors and using the same club name, sharing also the same club fan base, supporters and facilities.

Many professional sports clubs have an associate system where the affiliated supporters pay an annuity fee. In those cases, supporters become eligible to attend the club's home matches and exhibitions across the entire season, and have the right to practice almost every kind of sport at the club's facilities. Registered associate member fees, attendance receipts, sponsoring contracts, team merchandising, TV rights, and athlete/player transfer fees, are usually the primary sources of sports club financing. In addition, there are sports clubs, or its teams, which are publicly listed - several professional European football clubs belonging to a larger multisports club are examples of this (namely, Portuguese SADs (Sociedade Anónima Desportiva) such as Sport Lisboa e Benfica and Sporting Clube de Portugal, or Spanish SADs (Sociedad Anónima Deportiva) Real Zaragoza, S.A.D. and Real Betis Balompié S.A.D., as well as Italian clubs like Società Sportiva Lazio S.p.A.).

Some sports teams are owned and financed by a single non-sports company, for example the several sports teams owned by Red Bull GmbH and collectively known as Red Bulls. Other examples of this are the several sports teams owned by Bayer AG and Philips corporations through the Bayer 04 Leverkusen and PSV Eindhoven respectively, that originally were works teams, the teams owned by the Samsung Group (Samsung Sports), and the teams owned by the Anschutz Entertainment Group (AEG). They may compete in several different sports and leagues, being headquartered in some cases across several countries.

In the field of competitive club sports, an athlete will typically be registered to only one club for a given discipline and will compete for that club exclusively for the duration of a competition or season. Exceptions to this include player trades and transfers, athlete loan agreements and unattached trialists. Where an athlete competes in multiple disciplines, or where club membership has social or training aspects such as local athletic clubs, then athletes may register with multiple clubs.
