Frank Henry Willard (September 21, 1893 – January 11, 1958) was an American cartoonist best known for his syndicated newspaper comic strip Moon Mullins which ran from 1923 to 1991, working alongside assistant Ferd Johnson.

"[2] He next wrote and drew The Outta Luck Club for King Features (1919–23), where he also substituted for cartoonist Jean Knott on his Penny Ante poker panel.

In 1923, Joseph Patterson of the Chicago Tribune-New York News Syndicate wanted a lowlife strip to compete with Barney Google.

With Florida as a home base, Willard worked out of hotel rooms in Los Angeles, North Carolina, Maine and Wisconsin.

Characters in toppers sometimes turned up in the main strip, such as Kitty Higgins joining the cast of Moon Mullins and Herby appearing in Smitty.
