The Ig Nobel Prize (/ˌɪɡnoʊˈbɛl/ IG-noh-BEL) is a satiric prize awarded annually since 1991 to celebrate ten unusual or trivial achievements in scientific research.

Its aim is to “honor achievements that first make people laugh, and then make them think.” The name of the award is a pun on the Nobel Prize, which it parodies, and on the word ignoble. Organized by the scientific humor magazine Annals of Improbable Research (AIR), the Ig Nobel Prizes are presented by Nobel laureates in a ceremony at the Sanders Theater at Harvard University, and are followed by the winners’ public lectures at the Massachusetts Institute of Technology.

The 33rd First Annual Ig Nobel Prize ceremony happened on Thursday, September 14, 2023. The 2023 ceremony happened entirely as a webcast, not in a theatre. A New, Additional Event One Month After the Ceremony: there will be a new, companion event called Ig Nobel Face-to-Face. The new Ig Nobel Prize winners and other researchers will ask each other questions about their work. (There will also be music and paper airplanes and other good stuff.) This new event will happen in the new MIT Museum in Cambridge, Massachusetts, USA, on Saturday evening, November 11, 2023.
