Raymond Crawford Ewer was an early 20th-century newspaper and magazine cartoonist.

Born in 1888 in Napa County, California, the artist started his career in 1907 as a staff cartoonist for the San Francisco Call.

In the following year he started making some kids' and activity features for the McClure Syndicate, of which the paper doll feature 'Kid Cut Ups Puzzle' lasted the longest (from January through August 1909).

Between 1910 and 1914, Ewer was associated with World Color Printing, a company which produced Sunday comics sections for mainly rural newspapers.

Raymond Crawford Ewer was furthermore a cartoonist for the satirical weekly magazines Judge and Puck, and an illustrator for magazines like The Masses and Vanity Fair. He passed away from tuberculosis on 22 June 1915, at the age of only 26.
