Cowboy Henk is a Belgian absurd/surreal humour gag-a-day comic strip series drawn by Herr Seele and written by Kamagurka.

In 1981 Kamagurka published a one-off long-run comic strip named Mijnheerke Plagiaat ("Mister Plagiarism"), in the Belgian newspaper Vooruit (later De Morgen).

On April 10, 2013, the Flemish radio station Studio Brussel interviewed Seele and he announced Henk's comeback in HUMO.

The series has been translated into French (as Cowboy Maurice), Spanish, and English in magazines such as L'Echo des Savanes and RAW.

Cowboy Henk is a muscular adult male with a characteristically brawny chin and a long yellow quiff which, according to the jubilee story De Bananenkuif (2001) is made from bananas.

[4] Usually Henk wears a white T-shirt with short sleeves, blue pants and black shoes with round noses.

Herr Seele told in interviews that Zippy the Pinhead by Bill Griffith was a major inspiration.

Some Cowboy Henk gags have an almost child friendly atmosphere while others are full of shocking dirty jokes, toilet humour and/or black comedy.
