Harold Teen is a discontinued, long-running American comic strip written and drawn by Carl Ed (pronounced "eed").

Publisher Joseph Medill Patterson may have suggested and certainly approved the strip's concept, loosely based on Booth Tarkington's successful novel Seventeen.

In the 1928 Harold Teen film, the sundae is a soupy concoction of ice cream and hot chocolate which is eaten by "gedunking" a large ladyfinger cookie in it.

Reprints appeared in Dell's Popular Comics, and Whitman published a Better Little Book, Harold Teen in Swinging at the Sugar Bowl (1939).

Three different topper strips by Carl Ed ran on his page, positioned beneath Harold Teen: The Absent Minded Professor (January 4, 1931 to November 9, 1933), Josie (1935 to early 1940s) and Myrtle (1943 to 1951).

[citation needed] Kansas City jazz band pianist Joe Sanders wrote a song about the "Don Juan of comic strip fame", describing him as a "human love machine" and as "romance personified".
