Quackwatch

Quackwatch is a United States-based website, self-described as a "network of people" founded by Stephen Barrett, which aims to "combat health-related frauds, myths, fads, fallacies, and misconduct" and to focus on "quackery-related information that is difficult or impossible to get elsewhere". Since 1996 it has operated the alternative medicine watchdog website quackwatch.org, which advises the public on unproven or ineffective alternative medical remedies. The site contains articles and other information criticizing many forms of alternative medicine.

Quackwatch cites peer-reviewed journal articles and has received several awards. The site has been developed with the assistance of a worldwide network of volunteers and expert advisors. It has received positive recognition and recommendations from mainstream organizations and sources, although at times it has also received criticism for perceived bias in its coverage. It has been recognized in the media, which cite quackwatch.org as a practical source for online consumer information. The success of Quackwatch has generated the creation of additional affiliated websites; as of 2019 there were 21 of them.
