The National Vaccine Information Center (NVIC), founded under the name Dissatisfied Parents Together (DPT) in 1982, is an American 501(c)(3) organization that has been widely criticized as a leading source of fearmongering and misinformation about vaccines. While NVIC describes itself as the "oldest and largest consumer-led organization advocating for the institution of vaccine safety and informed consent protections", it promotes false and misleading information including the discredited claim that vaccines cause autism, and its campaigns portray vaccination as risky, encouraging people to consider "alternatives." In April 2020, the organization was identified as one of the greatest disseminators of COVID-19 misinformation on Facebook.

Despite its name, the National Vaccine Information Center bears no relation to the National Vaccine Advisory Committee, an advisory body of the United States Department of Health and Human Services.

Since 2003, the NVIC has maintained a website named Medalerts.org, which republishes the CDC's Vaccine Adverse Event Reporting System data without its appropriate méthodological transparency and warnings. This has led to misleading attributions of deaths to the COVID-19 vaccines.
