Kirr is an island in the Darss-Zingst Bodden Chain south of the Zingst Peninsula on the German Baltic Sea coast.

The island is a nature reserve within the Western Pomerania Lagoon Area National Park.

On the east side of the island is the small hamlet of Klein Kirr; in the north are the ruins of an old farmstead.

It is an ideal breeding ground for numerous birds, especially waders like dunlin, ruff, redshank, black-tailed godwit, oystercatcher, avocet and lapwing as well as the black-headed gull.

In autumn the island acts as a resting place for several thousand crane over several weeks as they migrate south.
