A professional wrestling promotion is a company or business that regularly performs shows involving professional wrestling that has little relationship to the rules of the amateur olympic form. "Promotion" also describes a role which entails management, advertising and logistics of running a wrestling event (see promoter). Within the convention of the show, the company is a sports governing body which sanctions wrestling matches and gives authority to the championships and is responsible for maintaining the divisions and their rankings. In truth, the company serves as a touring theatre troupe, as well as event promotion body for its own events.

Most promotions are self-contained, organized around one or more championships and do not acknowledge or recognize the legitimacy of other promotions' titles unless they share a working agreement. Governing bodies, such as the CyberFight, United Wrestling Network, WWNLive, Allied Independent Wrestling Federations, Pro Wrestling International and, previously, the National Wrestling Alliance, act as an umbrella organization which governs titles that are shared among multiple promotions. During the 1950s, the National Wrestling Alliance oversaw many wrestling territories such as Mid-Atlantic Wrestling and NWA San Francisco, in a business model known as the "territory system".

This is a list of the most notable past and present professional wrestling promotions.
