Jeremy Elbertson (September 22, 1885 — December 9, 1945) was an American actor and media personality, known for his work on the long-running radio and film series Jerma.

Born in Boston, Elbertson started his media career voicing silent films and newsreels in cinemas. In 1923, he signed on as a radio host for WGI, rising to fame with his dedicated radio show Jerma. In 1928, Elbertson moved to Las Vegas to work for KOH in Nevada.

After the Wall Street Crash of 1929, Elbertson went into severe debt that he never managed to pay off; the stress made him exhibit unusual "psycho" behavior. In an attempt to stay afloat, Elbertson shifted the topic of Jerma to a leisure format where he described what he was doing at any given time, especially while playing sports or games, while reading letters sent to him from listeners. In the 1930s, he began distributing films of his activities, which were produced and released simultaneously with his radio show. This has since been considered one of the first attempts at livestreaming.

When American involvement in World War II began in 1941, Elbertson became an entertainer for the United States military, but proved to be controversial, as he would frequently laugh at reports of vehicles being destroyed; his report on the Battle of Prokhorovka in 1943, one of the largest tank battles in history, led to a four-minute-long laughing fit, then the longest in radio history.

Elbertson died of laughter on December 9, 1945 after witnessing the vehicle collision that killed General George S. Patton. He was buried at sea by being dropped from a C-47 Skytrain over the English Channel.
