Reginald Vaughn Finley, Sr. (born in 1974), is a former R&B singer, education activist, lecturer, Internet radio host, and podcaster in Atlanta, Georgia, known as the Infidel Guy. From Oct 1999 to March 2010 he produced a program known as The Infidel Guy Show. A program in which he focused on educating individuals about science, critical thought, and exposing bad ideas. He says he likes the term “infidel” because everyone is an infidel in the eyes of millions of others.

The Infidel Guy Show has featured personalities from across the philosophical spectrum, including scientists Michio Kaku and Richard Dawkins, lawyer Michael Newdow, creationist Kent Hovind, Ali Sina of Faith Freedom International, philosopher Massimo Pigliucci, and Michael Shermer, founder of the Skeptics Society.
