De Haan (Dutch pronunciation: [də ˈɦaːn]; French: Le Coq, French pronunciation: [lə kɔk]; West Flemish: D'n Oane; English: The Cock or Cockerel; (USA/Canada) Rooster) is a place and a municipality located in the Belgian province of West Flanders.

The coastal village of De Haan proper has maintained a low skyline so its many buildings in Belle Époque style are still prominently visible.

[citation needed] Its most famous resident was Albert Einstein, who lived in the villa "Savoyarde" for six months in 1933 after leaving Nazi Germany.

Belgain TV crime drama series, Juliet (2024), was filmed and set in De Haan.
