HNLMS Karel Doorman (Dutch: Zr.Ms. Karel Doorman) is a multi-function support ship for amphibious operations of the Royal Netherlands Navy , which is also used by the German Navy. The ship replaced both of the navy's replenishment oilers: HNLMS Zuiderkruis (scrapped in February 2014) and HNLMS Amsterdam (sold to Peru in December 2014). At 204.7 metres (672 ft) she is the largest ship in service in the Netherlands navy.

She was built at the Damen yard in Galati, Romania, being the largest warship ever built in Romania. On 16 August 2013 the ship arrived in Vlissingen, The Netherlands where final outfitting and installation of the weapon systems took place. In September, 2013, it was announced that as part of a series of Dutch defense budget cuts, the vessel wouldn't enter military service, but this decision was reversed by the Dutch government. The vessel cost 400 million Euros.

On 4 February 2016, German minister Ursula von der Leyen, and Dutch minister Jeanine Hennis-Plasschaert signed the LOI on the Dutch Navy ship HNLMS Karel Doorman. The German Navy will now, in coordination with their Dutch counterparts, be able to use the biggest ship in the Dutch Navy.
