OpenTTD is an open source game engine for the Chris Sawyer game Transport Tycoon Deluxe.

OpenTTD duplicates the original game's features but also has numerous additions, including canals, revised rail station construction, and additional airports. Perhaps the most significant feature compared to the original game is its multiplayer capability. It offers LAN and Internet play via public and worldwide servers for up to eleven players. OpenTTD also includes numerous usability improvements not present in Transport Tycoon Deluxe.

OpenTTD incorporates many features from TTDPatch, and, like TTDPatch, is available under the GNU General Public License. Both OpenTTD and TTDPatch are not totally standalone games—while OpenTTD does not need the Transport Tycoon Deluxe executables, it needs the game's graphics files. However, there is currently an effort to devise a new graphics standard (and new graphics) to eliminate this need.

The game's legality has been questioned by some, since the initial versions were created by disassembling the binary from the official release.
