The official flag of Mayotte is the flag of France. The coat of arms of Mayotte is well defined and was adopted by the predecessor entity of the Department of Mayotte in 1982.

Mayotte is an overseas region and department of France. The French flag is thus the official flag accordingly to the second article of the constitution.^[1]

A banner is flown by the departmental council, consisting of the department's coat of arms on a white field with the words "DEPARTMENT DE MAYOTTE".^[2][3]

The coat of arms of Mayotte were created by Reunion Archives former director Michel Chabin and drawn by Pascale Santerre. The proposal was adopted by the former General Council of Mayotte on 23 July 1982 and assumed by the new department in 2011.^[4]

The blue and the red come from the flag of France, with the addition of a yellow shade for the two ylang-ylang flowers. The department's graphic charter gives the following color codes for the coat of arms:

The escutcheon, supported by two seahorses, reads as follows: Per fess azure a crescent argent and gules two ylang-ylang flowers or; within a bordure engrelled argent.

Finally, the whole is enframed at the top by Département and at the bottom by de Mayotte, with de written vertically. The font used is Barmeno Bold.
