King Features Syndicate, Inc. is an American content distribution and animation studio, consumer product licensing and print syndication company owned by Hearst Communications that distributes about 150 comic strips, newspaper columns, editorial cartoons, puzzles, and games to nearly 5,000 newspapers worldwide. King Features Syndicate also produces intellectual properties, develops new content and franchises (like The Cuphead Show!, which it produced with Netflix), and licenses its classic characters and properties.

King Features Syndicate is a unit of Hearst Holdings, Inc., which combines the Hearst Corporation's cable-network partnerships, television programming, distribution activities, and syndication companies. King Features' affiliate syndicates are North America Syndicate and Cowles Syndicate.

William Randolph Hearst's newspapers began syndicating material in 1895 after receiving requests from other newspapers. The first official Hearst syndicate was called Newspaper Feature Service, Inc., established in 1913. In 1914, Hearst and his manager Moses Koenigsberg consolidated all of Hearst's syndication enterprises under one banner (although Newspaper Feature Service was still in operation into at least the 1930s). Koenigsberg gave it his own name (the German word König means king) when he launched King Features Syndicate on November 16, 1915.

Production escalated in 1916 with King Features buying and selling its own staff-created feature material. A trade publication — Circulation — was published by King Features between 1916 and 1933. In January 1929, the world-famous Popeye character was introduced in King Features' Thimble Theater comic strip.

King Features had a series of hits during the 1930s with the launch of Blondie (1930–present), Flash Gordon (1934–2003 Note: Relaunched again in October 2023 by Dan Schkade as a daily and Sunday strip), Mandrake the Magician (1934–2013), and The Phantom (1936–present). In March 1936, a fictional, magical animal called Eugene the Jeep was added to Popeye, and trademarked.

King Features remained a "powerhouse" syndicate throughout the 1950s and the 1960s. In 1965 it launched a children's comic and coloring page.

In 1986, King Features acquired the Register and Tribune Syndicate for $4.3 million. Later that year, Hearst bought News America Syndicate (formerly Publishers-Hall). By this point, with both King Features and News America (renamed North America Syndicate), Hearst led all syndication services with 316 features.

In 2007, King Features donated its collection of comic-strip proof sheets (two sets of over 60 years' accumulation) to the Billy Ireland Cartoon Library & Museum and the Michigan State University Comic Art Collection while retaining the collection in electronic form for reference purposes.
