Zortech Ltd was a small British software company that marketed C and C++ compilers and associated software. The company was initially formed with the name Zorland Ltd to reflect its desire to be a direct competitor of Borland Inc. This was later changed to Zortech Ltd to avoid confusion.

Once established with a European market for their software, they created a sister company in the United States, Zortech Inc. At the same time the parent company was renamed again to Zortech International Ltd to reflects its expanded market. The company was eventually taken over in 1991 by Symantec Inc who wanted access to their compiler technology.

Zortech C Compiler is a fast optimising compiler for MS-DOS machines. The C compiler was known, in different times, as Datalight C compiler, then Zorland C and then Zortech C. The C++ compiler was known as Zortech C++ (the first commercial C++ compiler for Windows), later Symantec C++ and now Digital Mars C++ (DMC++).
