Ben Michael Goldacre is a British physician, academic, and science writer. Born on 20 May 1974, he is the first Bennett Professor of Evidence-Based Medicine and director of the Bennett Institute for Applied Data Science at the University of Oxford. He is a founder of the AllTrials campaign and OpenTrials, which aim to mandate open science practices in clinical trials.

Goldacre is particularly known for his Bad Science column in The Guardian, which he wrote from 2003 to 2011. He has authored four books: Bad Science (2008), a critique of irrationality and certain forms of alternative medicine; Bad Pharma (2012), an examination of the pharmaceutical industry and its practices; I Think You'll Find It's a Bit More Complicated Than That, a collection of his journalism; and Statins, about evidence-based medicine. Goldacre frequently delivers free talks about bad science and describes himself as a "nerd evangelist."
