Transport Tycoon (TT) and Transport Tycoon Deluxe (TTD) are Video games developed by Chris Sawyer and published by MicroProse in 1994 (TT), and 1995 (TTD). They are business simulation games, presented in an isometric view in 2D with graphics by Simon Foster, in which the player is in control of a transport company, and can compete against rival companies to make as much profit as possible by transporting passengers and various goods by road, rail, sea and air. The Deluxe version is an expanded and improved version of the original game.

Two Transport Tycoon games were released, dubbed Transport Tycoon and Transport Tycoon Deluxe. The deluxe version, as its name implies, is an expanded and improved version of the original game. (A "World Editor" expansion pack was also released for the original Transport Tycoon, but was overshadowed by the Deluxe version released shortly afterward; interestingly, it featured an alternate, Martian set of graphics, which did not appear in TTD).

Transport Tycoon for the Playstation is an enhanced version of the PC version of Transport Tycoon. You are in charge of a transport company starting in 1930 in the midst of The Great Depression, and your aim is to build up an empire of trains, ships, lorries, planes and helicopters, with technological evolution to be taken into account. The terrain is in real 3D, with hills and bridges taking effect. The things you can transport and earn money with range from passengers to oil right up to jewelery.
