Martinique is an overseas department of France, and therefore flies the flag of France.
The French national flag - the tricolore - consists of three vertical bands of equal width, displaying the country's national colors: blue, white and red. The blue band is positioned nearest the flag-staff, the white in the middle, and the red on the outside.
