The Caproni-Reggiane Ca.8000 was a four-engine seaplane passenger transport aircraft project for transatlantic crossings.

The project was started in the Reggiane technical office at that time in Clanezzo, Bergamo.

Designed to offer luxurious accommodation, the fuselage was divided in two decks, with beds in sleeping compartments and seats for 52 passengers; whilst for day flights the cabins sat 76, with ten crew members.

Facilities on-board included a restaurant, bar and meeting room, .
