The Jester of Columbia, or simply the Jester, is a humor magazine at Columbia University in New York City. Founded on April Fool's Day, 1901, it is one of the oldest such publications in the United States. Printed continuously at least through 1997, it was revived in 2001 after a short lapse in publication and again in 2005 after another, shorter one. Jester now produces magazines and sponsors comedy events on Columbia's campus.
