Jon Miller (born October 11, 1951 in San Francisco, California) is a Major League Baseball announcer. Since 1997 he has been the primary play-by-play voice of the San Francisco Giants, and since 1990 he has done national television and World Series radio broadcasts for ESPN.

Miller began his career with the Oakland Athletics in 1974. After brief stints with the Athletics, the Texas Rangers, and the Boston Red Sox, he was hired by the Baltimore Orioles in 1983. He remained the Orioles' primary announcer through 1996, before moving to the Giants. For a brief period in the 1970s, Miller also broadcast for the California Golden Seals of the National Hockey League.

A popular and respected broadcaster, Miller has received numerous honors for his play-by-play work, including a Cable ACE Award and several Emmy Award nominations.

In 2003, during a game between the Giants and Arizona Diamondbacks, Miller called a play involving two defensive errors by the Diamondbacks and at least three separate baserunning mistakes by Giants outfielder Ruben Rivera. When Rivera was finally thrown out at home plate trying to score what would have been the winning run, Miller angrily declared, "That was the worst baserunning in the history of the game!" The phrase was repeated numerous times on sports radio and highlight shows such as SportsCenter, and quickly became one of the most famous calls of Miller's long career. Rivera was released by the Giants the next day because of this play.
