Bernhard Gillam (April 28, 1856 – January 19, 1896) was an English-born American political cartoonist.
Gillam was born in Banbury, Oxfordshire. He arrived in New York with his parents in 1866. He worked as a copyist in a lawyer's office, but switched to the study of engraving, and later, after some of his cartoons had appeared in the New York Graphic, turned to cartooning. His work appeared in Frank Leslie's Illustrated Newspaper, Harper's Weekly, where he worked with Thomas Nast during James A. Garfield's campaign of 1880, and Puck magazine where he came under the influence of Joseph Keppler. Gillam also produced work for Judge, a magazine of which he became director-in-chief in 1886.
