Jason Mark Everman (born October 16, 1967) is an American musician and soldier who played guitar with Nirvana and Mind Funk, and bass in Soundgarden and OLD.

In a 2013 interview with The New York Times Magazine, Everman said when asked about his birthplace, "My birth certificate says Kodiak, but I'm pretty sure it was Ouzinkie, where my parents lived in a two-room cabin with a pet ocelot named Kia."

His parents had moved to the remote Spruce Island to, as guitarist and writer Clay Tarver put it, "get back to nature", but their marriage did not "work out".

His mother left with Jason when he was a toddler, moved to Washington, and married a former Navy serviceman; the family eventually settled in Poulsbo, across Puget Sound from Seattle.

Everman can also be seen in the bootleg video of Nirvana playing an "in store" performance at Rhino Records in Los Angeles on June 23, 1989.

In September 1994, influenced by Renaissance icon Benvenuto Cellini (who stated that a well-rounded man is an artist, warrior and philosopher), he left Mind Funk to enlist in the United States Army, subsequently serving with the Army's 2nd Ranger Battalion, Delta Company and later with the Special Forces, serving tours in Afghanistan and Iraq.

After receiving an honorable discharge in 2006, Everman went on to earn a Bachelor of Arts in philosophy from Columbia University School of General Studies on May 20, 2013.
