Definition
The Web Content Accessibility Guidelines (WCAG) are part of a series published by the Web Accessibility Initiative (WAI) of the World Wide Web Consortium (W3C), the main international standards organization for the Internet. They are a set of recommendations for improving web accessibility, primarily for people with disabilities—but also for all user agents, including highly limited devices, such as mobile phones. WCAG 2.0 was published in December 2008 and became an ISO standard, ISO/IEC 40500:2012 in October 2012. WCAG 2.2 became a W3C Recommendation on 5 October 2023.

The full Wikipedia article, linked below, goes much deeper into the history and the standards bodies behind it — we keep this glossary short on purpose so it stays useful as a quick reference.
