Peter C. Gøtzsche is a Danish physician, medical researcher, and leader of the Nordic Cochrane Center at Rigshospitalet in Copenhagen, Denmark. He co-founded, and has written numerous reviews within the Cochrane collaboration.

Among his research findings are that placebo has surprisingly little effect and that many meta-analyses may have data extraction errors. Gøtzsche and his coauthors have been keen to criticize the research methods and interpretations of other scientists, e.g. in meta-analysis of placebo.

Gøtzsche has commented on meta-analysis and the editorial independence of medical journals. He has written about issues surrounding medical ghostwriting with the position that it is scientific misconduct. He has also criticized the widespread use of SSRI antidepressants.
