Bill Mercer is an American sportscaster, originally from Muskogee, Oklahoma, who now lives in Richardson, Texas. His career spans over 60 years and has included broadcasting stints with the Dallas Cowboys, the Texas Rangers, North Texas State University (now known as the University of North Texas) football and basketball and many other D/FW regional teams. Perhaps he is most famously known for his work in the 1980's as the host and play by play announcer for World Class Championship Wrestling (WCCW), based in Dallas.

Mercer has spent over 50 years teaching new generations of sports broadcasters at the University of North Texas.

In 2002, he was inducted into the Texas Radio Hall of Fame.

Mercer was one of many news reporters who covered the John F. Kennedy assassination in 1963, which prompted him and others to write a book, When the News Went Live, about their experiences during that time.
