The term Galindians may be applied to two distinct, and now extinct, tribes of the Balts. Most commonly, the term is used to describe the Western Galindians who lived in the southeast part of Prussia. Less commonly, it is used for a tribe that lived in the area of what is today Moscow.

The name "Galinda" is thought to derive from the Baltic word *galas ("the end"), alluding to the fact that they settled for some time further west and further east than any other Baltic tribe.

Western Galindians

The Western Galindians (Old Prussian: *Galindis, Latin: Galindae) were at first a West Baltic tribe, and later the Old Prussian clan, which lived in Galindia, roughly the area of present-day Masuria but including territory further south in would become the Duchy of Masovia. It was adjacent to the territory of the Yotvingians, which is today in Podlaskie Voivodeship.

The name Galind- is probably derived from the hydromym of Gielądzkie Jezioro ( 53° 52' N 21° 10' E ) in the province of Olsztyn, in what was the very center of ancient Galindia. J. Nalepa (1971) suggested the root *gal- was originally a different ablaut grade of the same root found in Lith. "gilus" - deep, and "gelme" - depth. The original meaning referred to the depth of the lake mentioned, which is one of the deepest in the area. Nalepa, Jerzy, 'Próba nowej etymologii nazwy Galindia czyli Golędź.', Opuscula.

Ptolemy was the first to mention the Galindians (Koine Greek: Galindoi - Γαλίνδαι ) in the 2nd century AD. From the 6th/7th century until the 1600s the former central part of the Galindian tribe continued to exist as the Old Prussian clan of *Galindis. The language of the Old Prussians in Galindia became extinct by 1600s, mainly because of the 15th and 16th centuries influx of Protestants seeking refuge from Catholic Poland into Galindian area and German-language administration of Prussia.

Eastern Galindians

The Eastern Galindians (East Galindian: *Galindai, Russian: Goliadj, голядь, from Old East Slavic *Golędĭ) is an extinct East Baltic tribe, which from the 4th century lived in the basin of the Protva River, near the modern Russian towns of Mozhaysk, Vereya, and Borovsk. It is probable that the Eastern Galindians, as the bearers of the Moshchiny culture, also occupied all the Kaluga Oblast, until the Early East Slavs peopled the Moshchiny culture's area at the turn of 7th and 8th centuries Седов В.В., Восточные славяне в VI-XIII вв., М., 1982, c. 41-45..

The Russian chronicles first mention Eastern Galindians as Goliadj in 1058. Prince Yuri (George) the Long Arms (Yury Dolgoruky arranged a campaign against them in 1147, the year he founded Moscow in the land of the Galindians. After that, the Eastern Galindians are not mentioned in chronicles. Nevertheless, it's likely that they were not completely assimilated by Russians until the 15th (or 16th) century..

There were people who still identified themselves as Goliads in the 19th century.
