The Melzer See or Melzersee is a lake at Waren in Mecklenburgische Seenplatte, Mecklenburg-Vorpommern, Germany.

The Melzer See lies on the northeastern perimeter of the town of Waren (Müritz).

The location between two lakes was the occasion for the origin of the name of the Waren quarter of Werdersiedlung.

Whilst small gardens are ranged along its southern shore, the Melzer See is bordered to the northwest by meadowland.

The Ice Age Trail along theTiefwarensee also runs past the Melzer See.
