The first investigations of the mite fauna of Sable Island, Nova Scotia, Canada, are reported. Fourteen species have been found. Uropoda orbicularis (Müller) (Uropodidae) and Scarabaspis inexpectatus (Oudemans) (Eviphididae) are newly recorded for North America, Macrocheles nemerdarius Krantz and Whitaker (Macrochelidae) is newly recorded for Canada, and Trichoribates striatus Hammer (Ceratozetidae) is recorded for the first time south of the subarctic zone. Colonization, dispersal, and the zoogeographic origins of the fauna are discussed in the context of the biological, geological, and human history of the island. Cet article présente les premières investigations de la faune acarienne de l'Île de Sable en Nouvelle-Écosse au Canada. On a trouvé 14 espèces. On signale le Uropoda orbicularis (Müller) (Uropodidae) et le Scarabaspis inexpectatus (Oudemans) (Eviphididae) pour la première fois en Amérique du Nord, le Macrocheles nemerdarius Krantz et Whitaker (Macrochelidae) pour la première fois au Canada et le Trichoribates striatus Hammer (Ceratozetidae) pour la première fois au sud de la zone subarctique. La colonisation, la dispersion et les origines zoogéographiques de cette faune sont abordées dans le contexte de l'histoire biologique, géologique et humaine de l'île.
