Grootegast (Dutch pronunciation: [ˈɣroːtəˌɣɑst] ⓘ; Gronings: Grodegast; West Frisian: Gruttegast) is a village and former municipality in the northeastern Netherlands.

[3] The former municipality contained the population centres: Doezum, Enumatil, Faan, Grootegast, Kornhorn, Lutjegast, Niekerk, Oldekerk, Opende, Sebaldeburen.

The village originated around the year 1000 (as Majorgast) and was profiled from 1400 onwards as the counterpart of Lutjegast.

The name of the village refers to a gast or gaast, a higher, sandy ridge in an otherwise swampy area.

Linguistically, the influences of three provinces are noticeable: the dialect is a variant of Gronings, but in terms of intelligibility it is more like Drents; however, the accent and grammar sound rather Frisian, which can be explained by the fact that almost all of Lutjegast still spoke Frisian 100 years ago.
