Monkey Island is a series of adventure games. The first four games in the series were produced and published by LucasArts, earlier known as Lucasfilm Games. The fifth installment of the franchise was developed by Telltale Games in collaboration with LucasArts. A sixth game was developed by Terrible Toybox in cooperation with Lucasfilm Games and Devolver Digital.

The games follow the misadventures of the hapless Guybrush Threepwood as he struggles to become the most notorious pirate in the Caribbean, defeat the plans of the evil undead pirate LeChuck and win the heart of Governor Elaine Marley. Each game's plot usually involves the mysterious Monkey Island and its impenetrable secrets.

The first game in the series was created by Ron Gilbert, Tim Schafer and Dave Grossman. Gilbert worked on the first two games before leaving LucasArts. Grossman and Schafer, who also worked on the first two games, enjoyed success on other games before they both left LucasArts. The rights to Monkey Island remained with LucasArts, and the third and fourth games were created without direct involvement from the original writing staff. Dave Grossman was the project leader of the fifth game in the series and Gilbert was involved with the first design of the game. Gilbert's studio developed the sixth game, Return to Monkey Island, with Grossman assisting.
