Mahajanga [maːˈdzaŋɡə̥] (French: Majunga) is a city and an administrative district on the northwest coast of Madagascar.

Mahajanga is a favorite tourist destination for Malagasy tourists and international travelers, with beautiful beaches, a coconut-lined boardwalk ("Le Bord", short for "Bord de la mer" or sea-side), and eight months of hot, virtually rain-free weather.
