Bardowick (Bewick in Low Saxon) is a municipality in the district of Lüneburg in Lower Saxony, Germany.

Bardowiek was founded in the 8th century by Charlemagne, who established a bishopric in it, and until its destruction by Henry the Lion in 1189, it was the most prosperous commercial city of north Germany.

Its name is derived from the Longobardi, the tribe for whom it was the home and centre, and from it the colonization of Lombardy started.

In 1186 the then competent Prince-Bishop of Verden, Tammo (d. 1188), further privileged the collegiate church.

Today's building of the former collegiate, meanwhile Lutheran church (German: Bardowicker Dom, with Dom being used in German language - pars pro toto - as a synecdoche for collegiate churches and cathedrals alike) was erected between 1389 and 1485.
