Mürwik (Danish: Mørvig) is a community of Flensburg in the north of the German state of Schleswig-Holstein.

Situated on the east side of the Flensburg Firth, it is on the Angeln peninsula.

Mürwik is also known for the sail training ship Gorch Fock of the Naval Academy Mürwik and for the database of traffic violators of Germany (Kraftfahrt-Bundesamt, often short: KBA).

The highest hill of Mürwik is the Berg beim Eichenkratt.

The Bunkerberg, a hill over a bunker beside the KBA, is overgrown by trees.
