Captain Archibald Haddock is a character in the comic series 'The Adventures of Tintin', by Belgian cartoonist Hergé (Georges Prosper Remi). The cynical seaman is known for his colourful vocabulary and sarcastic comments. The 'Tintin' series began in the 1920s, however, Captain Haddock first appeared in 1941 as a counterpoint to the main character and hero, Tintin.

The stories focus on a young reporter from Belgium named Tintin, who travels the world with his dog, Snowy. In 1941, a bearded drunk man with a temper appeared in 'The Crab with the Golden Claws'. This was Captain Haddock and, despite his appearance and gruffness, soon became a good friend. Other popular characters in the series include a scientist called Professor Cuthbert Calculus, and two silly detectives called Thomson and Thompson.

Fictional sailors were often known for their expletives, but Hergé could not use swear words because the comic was aimed at children. Instead, he made up amusing sentences and words for Captain Haddock. Phrases include, "Billions of blue blistering barnacles!", "Ten thousand thundering typhoons!", and "fancy-dress freebooter".

'The Adventures of Tintin' was originally written in French, so some of the names differ between the French and English versions. Snowy, for instance, is 'Milou', and Thomson and Thompson are 'Dupont et Dupond'. Captain Haddock is the same in both languages. Hergé was inspired by his wife's cooking of "a sad English fish - haddock.”
