Charlie Slowes (born c. 1961) is an American sportscaster. Slowes is the radio play-by-play announcer for the Washington Nationals. He can be heard commentating every Washington Nationals game on the FM radio station 106.7 "The Fan" in the Washington D.C. metropolitan area .
A native of The Bronx, New York City, and a 1983 graduate of Fordham University, Slowes had also called play-by-play for the Baltimore Orioles and New York Mets. He began his career at KMOX Radio in St. Louis where he worked alongside broadcasting greats Jack Buck and Bob Costas. He has also worked for ESPN, NBC Sports, CBS Radio Sports, Mutual/Westwood One, SportsPhone, and the minor league AAA Tidewater Tides. Slowes was also the radio voice of the Washington Bullets (later to became the Washington Wizards) from the 1986–87 NBA season to the 1996–97 NBA season. After 11 seasons with the Bullets, he joined the expansion Tampa Bay Devil Rays in 1998 as their radio play-by-play announcer, a position he held until 2004 when he joined the Nationals the next year. Since 2006, he has teamed with Dave Jageler for Washington Nationals broadcasts.
Slowes's broadcasting style typically features home run calls of "Going, going, gone, goodbye!" and "Bang, zoom goes [players name]!"
After every game the Nationals win, Slowes announces "A Curly W [referring to the Nationals' logo] is in the books" 
After a poor baserunning decision gets a runner out, Slowes often questions, "What was he thinking, what was he watching, where was he going?"
