Mayda (variously known as Maida, Mayd, Mayde, Brazir, Mam, Asmaida, Asmayda, Bentusle, Bolunda and Vlaanderen) is a non-existent island in the North Atlantic that has been shown on several published maps at various points in history. It was most often represented as being crescent-shaped and its position has varied widely over time. Early maps drew the island west of Brittany and southwest of Ireland, but it later moved towards the Americas (Newfoundland, Bermuda, West Indies). It was shown on a Rand McNally relief map as late as 1906.
The island first appeared under the name of Brazir, on the Pizigani brothers' 1367 map. It was crescent shaped and sited southwest of the island of Brasil, on the same latitude of southern Brittany.
While submerged land of the appropriate shape has been found in the area of early maps (at , 20 fathoms down), it is not necessarily that of Mayda.
