The Timex Computer 2048 or TC 2048 is a 1984 computer developed by Timex Portugal (the Portuguese branch of Timex Corporation), at the time part of Timex Sinclair. It was based on the Timex Sinclair 2048 prototype (see below), with a similar redesign case, composite video output, Kempston joystick interface, and additional video modes, while being highly compatible with the Sinclair ZX Spectrum computer (although ROM differences prevented 100% compatibility).

After connecting an external disk drive, Timex FDD3000, the computer could work under TOS - Timex Operating System or CP/M.

As Timex Portugal sold the Timex Sinclair models in Portugal and Poland under the Timex Computer brand, this computer is named "Timex Computer 2048", even though the "Timex Sinclair 2048" was never produced.
