The Ebbe Nielsen Prize was an international science award made annually between 2002 and 2014 by the Global Biodiversity Information Facility (GBIF), to recognize a researcher who had made substantial contributions to the field of biodiversity informatics. The prize was established in memory of prominent entomologist and biodiversity informatics proponent Ebbe Nielsen, who died of a heart attack in the U.S.A. en route to the 2001 GBIF Governing Board meeting.
