Grömitz (German pronunciation: [ˈɡʁøːmɪts] ⓘ) is a municipality in the district of Ostholstein, in Schleswig-Holstein, Germany.

It is situated on the Bay of Lübeck, approximately 35 km northeast of Lübeck, and 23 km east of Eutin.

In fair weather one can see buildings on the about 15 kilometer distant shore.

[clarification needed] The town name contains the Slavic root grom ("thunder") and means "a place of thunder".

There were three ligers in the local zoo, but the last one had to be put to rest in February 2008.
