Zak McKracken and the Alien Mindbenders is a 1988 graphic adventure game by Lucasfilm Games. It was the second game to use the SCUMM engine, after Maniac Mansion. The project was led by David Fox, with Matthew Alan Kane as the co-designer and co-programmer.

Like Maniac Mansion, it was developed for the Commodore 64 and later released in 1988 for that system and DOS.

The story is set in 1997, nine years after the game's production. The plot follows Zak, a writer for the National Inquisitor, a tabloid newspaper; Annie Larris, a freelance scientist; and Melissa China and Leslie Bennett, two Yale University coed students, in their attempt to prevent the nefarious alien Caponians (who have taken over "The Phone Company", an amalgamation of various telecommunication companies around the world) from slowly reducing the intelligence of everybody on Earth by emitting a 60 Hz "hum" from their "Mind Bending Machine". The Skolarians, another ancient alien race, have left a defense mechanism hanging around to repulse the Caponians (the "Skolarian Device"), which needs reassembly and start-up. Unfortunately, the parts are spread all over Earth and Mars.
