The Sci-Fi Dine-In Theater Restaurant is a theme restaurant at Disney's Hollywood Studios, one of the four main theme parks at Walt Disney World in Bay Lake, Florida, United States. Established in May 1991, the restaurant is modeled after a 1950s drive-in theater. Walt Disney Imagineering designed the booths to resemble convertibles of the period, and some servers act as carhops while wearing roller skates. While eating, guests watch a large projection screen displaying clips of 1950s and 1960s films as Frankenstein Meets the Space Monster, Plan 9 from Outer Space, and Attack of the 50 Foot Woman.

The restaurant serves traditional cuisine of the United States. Popcorn functions as a complimentary hors d'oeuvre. Initially, the menu listed items with themed names, such as "Tossed in Space" (garden salad), "The Cheesecake that Ate New York", and "Attack of the Killer Club Sandwich", but these playful names were later altered so that they now describe the dishes in a more standard and straightforward manner.
