John M. Most (June 15, 1923 – January 3, 1993) was an American sports announcer, known primarily as the raspy radio voice of the Boston Celtics of the National Basketball Association from 1953 to 1990.

Born to Jewish parents in New York City, he was named after his paternal grandfather, the German-American anarchist newspaper editor and orator Johann Most.

After distinguished Air Force service in World War II (see below), he began his basketball broadcasting career in the late 1940s as a protégé of New York Knickerbockers announcer (and 1936 Olympics track star) Marty Glickman.

Sponsored by Wheaties and Blackstone cigars, this short scoreboard program consisted of Most reading the scores and rattling off pitching changes and home runs.

As an aerial gunner on a B-24 Liberator he flew 28 combat missions with the 15th Air Force in World War II, earning seven medals.

Shortly after VE Day, as his unit broke camp in central Italy, Johnny wandered up a nearby hillside to a graveyard filled with American flags, his final visit to fallen comrades before returning home to the Bronx.

[4] A heavy smoker for his entire adult life, Most was plagued with health problems beginning in 1983, when he suffered a stroke that left his right hand permanently paralyzed.

On December 3 of that year, Most was honored with permanent installation of his personal microphone at Boston Garden, silver-plated and encased in a Celtic-green frame and attached to the façade of the vantage point Most had always described as "high above courtside".
