Operation Warp Speed (OWS) was a public–private partnership initiated by the United States government to facilitate and accelerate the development, manufacturing, and distribution of COVID-19 vaccines, therapeutics, and diagnostics. The first news report of Operation Warp Speed was on April 29, 2020, and the program was officially announced on May 15, 2020. It was headed by Moncef Slaoui from May 2020 to January 2021 and by David A. Kessler from January to February 2021. At the end of February 2021, Operation Warp Speed was transferred into the responsibilities of the White House COVID-19 Response Team.

The program promoted mass production of multiple vaccines, and different types of vaccine technologies, based on preliminary evidence. Then there were clinical trials. The plan anticipated that some of these vaccines would not prove safe or effective, making the program more costly than typical vaccine development, but potentially leading to the availability of a viable vaccine several months earlier than typical timelines.

Operation Warp Speed, initially funded with about $10 billion from the CARES Act (Coronavirus Aid, Relief, and Economic Security) passed by the United States Congress on March 27, 2020, was an interagency program that includes components of the Department of Health and Human Services, including the Centers for Disease Control and Prevention, Food and Drug Administration, the National Institutes of Health (NIH), and the Biomedical Advanced Research and Development Authority (BARDA); the Department of Defense; private firms; and other federal agencies, including the Department of Agriculture, the Department of Energy, and the Department of Veterans Affairs.
