This is a list of the world's longest wooden ships. The vessels are sorted by ship length including bowsprit, if known. Finding the world's longest wooden ship is not straightforward since there are several contenders, depending on which definitions are used. For example, some of these ships benefited from substantial iron or even steel components since the flexing of wood members can lead to significant leaking as the wood members become longer. Some of these ships were not very seaworthy, and a few sank either immediately after launch or soon thereafter. Some of the more recent large ships were never able or intended to leave their berths, and function as floating museums. Finally, not all of the claims to the title of the world's longest wooden ship are credible or verifiable.
