Glenn Harlan Reynolds is Beauchamp Brogan Distinguished Professor of Law at the University of Tennessee, and is best known for his weblog, Instapundit, one of the most widely read American political weblogs.

Reynolds is often described as conservative, but in fact holds liberal views on social issues such as abortion, the War on Drugs and gay marriage. He describes himself as a libertarian and more specifically a libertarian transhumanist. He once illustrated his combination of views by stating: "I'd be delighted to live in a country where happily married gay couples had closets full of assault weapons." He is a strong supporter of Porkbusters and the Iraq War.
