Marr () is one of six committee areas in Aberdeenshire, Scotland. It has a population of 34,038 (2001 census). Someone from Marr is called a Màrnach in Scottish Gaelic.
Etymology
The genesis of the name Marr is uncertain. Further possibilities include a connection with the ethnic names Marsi and Marsigni of Italy and Bohemia, or a derivation from Old Norse marr meaning "sea, marsh, fen".
American academic Thomas Clancy has noted cautiously the similarity between the territory names Buchan and Marr to those of the Welsh commotes Cantref Bychan and Cantref Mawr, meaning "large commote" and "small commote", respectively. Linguist Guto Rhys adjudged the proposal "appealing" but "questionable", on the basis that the form Marr conflicts with the expected development of mawr.
Between them the three wards elect ten councillors to the 68-member council.
Historic province
thumb|left|200px|Map of Scotland showing the historic district of MarMarr is named after Mar, one of the historic provinces of Scotland, extending from north of the Don southward to the Mounth. Like other such areas, it was under the rule of a mormaer in the Middle Ages. In the mid-19th century, local government reforms replaced the ancient provinces with new counties (shires), aligned to sheriffdom boundaries; hence, Marr became the southern portion of the shire of Aberdeen.
