Formartine (Scottish Gaelic: Fearann Mhàrtainn meaning "Martin's land") is a committee area in Aberdeenshire, Scotland. This district extends north from the River Don to the River Ythan. It has a population of 36,478 (2001 Census).
Formartine has experienced rapid population growth, particularly around Ellon and Oldmeldrum, and in the south east where development has spread outwith the city of Aberdeen. By contrast, the area around Turriff retains strong dependency on the traditional agricultural economy. The area's coastline and rural environment offer recreation potential including the Formartine and Buchan Way.
