Dennis Miller (November 3, 1953) is a 5-time Emmy winning American stand-up comedian, political commentator, actor, sports commentator, and television and radio personality. He is known for his ability to improvise critical assessments laced with pop culture references. He rose to fame as a cast member of Saturday Night Live in 1985, and subsequently hosted a string of his own talk shows on HBO, CNBC and in syndication. He currently hosts a daily, three-hour, self-titled talk radio program, nationally syndicated by Westwood One.

In recent years, Miller has become known for his political opinions, emphasizing a hawkish stance on U.S. military action and supporting Republican presidential candidates. He is a regular political commentator on Fox News Channel's The O'Reilly Factor in a segment called "Miller Time", and formerly on the network's Hannity & Colmes in a segment called "Real Free Speech."

Miller was born in Pittsburgh, Pennsylvania and grew up in Castle Shannon, a suburb of Pittsburgh, where he graduated from Keystone Oaks High School in 1971. His parents separated and Miller was raised by his mother, Norma, a dietitian. Miller is of Scottish descent. At Point Park University, he majored in journalism because he thought it would be easy: "I remember seeing All the President's Men and thinking Redford looked cool in his crinkled tie." He was a member of Sigma Tau Gamma Fraternity. About his social status during this period, Miller writes: "When I went to college, I lived on campus, and the guys I hung out with made me do some things I'm not proud of, although they made the characters in Revenge of the Nerds look like the Rat Pack in 1962. I myself made that kid Booger look like Remington Steele" (I Rant, Therefore I Am).
