Pellworm (Danish Pelvorm) is one of the North Frisian Islands on the North Sea coast of Germany. It is part of the Nordfriesland district in the federal state of Schleswig-Holstein.

In medieval times Pellworm was a part of the larger island of Strand which was torn into pieces in a disastrous storm tide in 1634. Other remnants of Strand are Nordstrand and the Halligen.

Pellworm is accessible by a ferry departing from the neighbouring peninsula of Nordstrand (which is in turn connected with the mainland by a road causeway).

One of the largest hybrid renewable energy plants in Europe is to be found on Pellworm [1]. It combines photovoltaic and wind energy to provide over 700MWh/y of electricity.

Together with several smaller islands, Pellworm forms the Amt Pellworm.
