Nordwestmecklenburg (Northwestern Mecklenburg) is a Kreis (district) in the north-western part of Mecklenburg-Vorpommern, Germany. It is situated on the coast of the Baltic Sea and borders on Schleswig-Holstein to the west. Neighboring districts are (from east clockwise) Rostock, Ludwigslust-Parchim and the district-free city Schwerin, and the district Lauenburg and the district-free city Lübeck in Schleswig-Holstein. The district seat is the town Wismar.^[2]

The district is roughly situated in a triangle between the towns of Lübeck, Rostock and Schwerin.

In the north there is the coast of the Baltic Sea with the small island of Poel.

Nordwestmecklenburg District was established in 1994 by merging the previous districts of Gadebusch, Grevesmühlen and Wismar; along with smaller parts of the districts of Sternberg and Schwerin-Land. In the 2011 district reform, it was merged with the formerly district-free town Wismar.^[2] The name of the district was decided by referendum on 4 September 2011.^[3]

“Party per pale Or and Azure, dexter the half crowned bull's head Sable of Mecklenburg, sinister a bishopric staff Or”. The staff symbolizes the diocese of Ratzeburg, which in 1648 became the Principality of Ratzeburg. It also stands for the diocese of Schwerin. Also the Hanseatic city of Wismar is represented in red-white.

The coat of arms was designed by the designer and heraldic Heinz Kippnick, and was granted on July 1, 1996.
