Don't Give Up the Ship is a set of rules for conducting Napoleonic era naval wargames. The game was published by Guidon Games in 1972 and republished by TSR, Inc. in 1975. The game was developed as a collaboration between Dave Arneson, Gary Gygax, and Mike Carr. It was the first collaboration between Dave Arneson and Gary Gygax, the co-authors of Dungeons & Dragons. Mike Carr edited the rules and researched the historical single ship actions that are included as game scenarios.

David Lance Arneson was an American game designer best known for co-developing the first published role-playing game (RPG), Dungeons & Dragons, with Gary Gygax, in the early 1970s. Arneson's early work was fundamental to the role-playing game (RPG) genre, pioneering devices now considered to be archetypical, such as cooperative play to develop a storyline instead of individual competitive play to "win" and adventuring in dungeon, town, and wilderness settings as presented by a neutral judge who doubles as the voice and consciousness of all characters aside from the player characters.
