Jet Set Willy II: The Final Frontier is a platform game released in 1985 by Software Projects for a variety of 8-bit home computers. It was the only official sequel to Jet Set Willy, one of the most successful and popular home computer games ever released. Officially, Jet Set Willy II: The Final Frontier is the last of the Miner Willy series, although numerous unofficial sequels, remakes, homages and updates have been released, even up to this day.

Jet Set Willy II is an expansion of the original JSW rather than a new game unto itself. Its map is primarily an expanded version of the original mansion, with only a few new original elements over its predecessor, several of which are based on rumoured events in JSW that were in fact never programmed (such as being able to launch the titular ship in the screen called "The Yacht" and explore an island). In the ZX Spectrum, Amstrad and MSX versions Willy is blasted from the Rocket Room into space, and for these 33 rooms he dons a spacesuit.

Due to the proliferation of hacking and cheating in the original game Jet Set Willy II pays homage to this and includes a screen - appropriately called Cheat - that can only be accessed by cheating.

Control of Willy also differs from the original:

Jet Set Willy II was not written by the original programmer, Matthew Smith, and was instead developed by Derrick P. Rowson.

The ending of JSW II is also different. Once Willy has collected 150 of the 175 available items and goes to bed, the game takes control of Willy and guides him into the bathroom, where he falls into the toilet - and lands in a room named Oh $#!+! The Central Cavern!, laid out identically to and deriving its name from the opening level of Manic Miner. The screen is playable on the Amstrad CPC version, but there is no escape, save for the player intentionally killing off their remaining lives.
