Charlie O'Donnell is a television announcer best known as the "voice of the Wheel" on Wheel of Fortune.

O'Donnell began his career in 1958, working with Dick Clark on American Bandstand. This led to several stints as a disc jockey on Los Angeles radio, and later as news anchorman on Southern California television.

He also made a full-time career as an announcer on many television shows throughout the decades, with such series as The Joker's Wild, Tic Tac Dough, Card Sharks, The $100,000 Pyramid, and The Price Is Right. He has also served as announcer for the American Music Awards, the Emmy Awards, and the Academy Awards.

But the show for which he is best known is Merv Griffin's Wheel of Fortune. Griffin himself knew the only person who could serve as the show's thunderous announcer was Charlie O (as O'Donnell is otherwise called). O'Donnell has served as the show's announcer from episode one in 1975, with the exception of a period in the 1980s when Jack Clark and M.G. Kelly served as announcers (due to a commitment to Pyramid). In 1989, O'Donnell returned as permanent Wheel announcer. His most famous shout on the series is "...twenty five th-oooooooooo-sand dollars!" (or higher, depending on the amount of money won in the show's bonus round).
