Charles John O'Donnell (August 12, 1932 – November 1, 2010) was an American radio and television announcer, primarily known for his work on game shows, and for his distinctive baritone voice.

[2] This led to several stints as a disc jockey on Los Angeles radio (most notably on Pasadena station KRLA, 1964–67), and later as news anchorman and staff announcer on Los Angeles television station KCOP-TV, where he performed double duty and often introduced his own newscasts with the self-referential cue "and now Charlie O'Donnell with the news."

Additionally, Barry & Enright Productions taped The Joker's Wild and Tic-Tac-Dough at KCOP during its initial syndicated runs, which O'Donnell announced for.

He 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, Bullseye and The $100,000 Pyramid (again working with Dick Clark).

Among the game show companies O'Donnell worked for as a primary announcer were Merv Griffin Enterprises/Sony Pictures Television (1975–87 and 1989–2010), Barry & Enright Productions (1981–86), and Barris Industries/The Guber-Peters Entertainment Company (1986–89) He also announced game shows for Mark Goodson-Bill Todman Productions (including Card Sharks, Trivia Trap, To Tell the Truth); Bob Stewart Productions (The $100,000 Pyramid); Hill-Eubanks Group's All Star Secrets and The Guinness Game; and Scotti Bros.-Syd Vinnedge's Wordplay.

O'Donnell died at his home in Sherman Oaks, California, of congestive heart failure at the age of 78 on the morning of November 1, 2010.
