Eendracht or Eendragt ("Unity") was a First Charter (i.e. first rate) two-decker ship of the confederal navy of the United Provinces (a precursor state of the Netherlands) between 1666 and 1689. Eendragt was the more common spelling in the 17th century; Eendracht is the modern Dutch standard spelling.
Eeendracht was built from 1665 to 1666 for the Maas Admiralty, one of the five naval forces of the Dutch Republic, as a replacement for the earlier ship of the same name that had been sunk in June 1665 at the Battle of Lowestoft. The new ship was the flagship of Lieutenant-Admiraal Aert van Nes at the Four Days' Battle of 1666 and at the subsequent St James' Day Battle.
