Nick Gillespie is editor in chief of Reason.tv and Reason.com, which draws 2.5 million visits per month and features the staff weblog Hit & Run, named by Playboy, Washingtonian, and others as one of the best political blogs.

Gillespie served as Reason magazine's editor in chief from 2000 to 2008. Under his direction, Reason won the 2005 Western Publications Association "Maggie" Award for Best Political Magazine. Gillespie originally joined Reason's staff in 1993 as an assistant editor and ascended to the top slot in 2000. In 2004, Gillespie edited the book Choice: The Best of Reason, an anthology of the magazine's best articles.

The Washington Post featured Gillespie's tenure at Reason magazine, asking, "Which monthly magazine editor argues that the spread of pornography is a victory for free expression? And that drugs from marijuana to heroin should not only be legalized, but using them occasionally is just fine? And is also quite comfortable with gay marriage? The answer is Nick Gillespie, libertarian and doctor of literature, who...is injecting [Reason magazine] with a pop-culture sensibility."

Gillespie's work has appeared in The New York Times, The Washington Post, The Wall Street Journal, The Los Angeles Times, The New York Post, Slate, Salon, Time.com, Marketplace, and numerous other publications. He was a regular contributor to the late, lamented satire site, Suck, where he wrote under the name Mr. Mxyzptlk.

He is a frequent commentator on radio and television networks such as National Public Radio, CNBC, CNN, C-SPAN, Fox News Channel and MSNBC. He has also worked as a reporter for several New Jersey newspapers and as an editor at several Manhattan-based music, movie, and teen magazines. He is almost certainly the only journalist to have interviewed both Ozzy Osbourne and the 2002 Nobel laureate in economics, Vernon Smith.

In 1996, Gillespie received his Ph.D. in English literature from the State University of New York at Buffalo. He also holds an M.A. in English with a concentration in creative writing from Temple University and a B.A. in English and Psychology from Rutgers University. Gillespie, the father of two sons, lives in Washington, DC, and Oxford, Ohio.
