Active Oberon is a general purpose programming language developed during 1996-1998 by the group around Niklaus Wirth and Jürg Gutknecht at the Swiss Federal Institute of Technology (ETH) in Zürich. It is an extension of the programming language Oberon. The extensions aim at implementing active objects as expressions for parallelism. Compared to its predecessors, Oberon and Oberon-2, Active Oberon adds objects (with object-centered access protection and local activity control), system-guarded assertions, preemptive priority scheduling and a changed syntax for methods (aka type-bound procedures in the Oberon terminology). Objects may be active, which means that they may be threads or processes. The operating system A2 aka Bluebottle, especially the kernel, synchronizes and coordinates different active objects.

Unlike Java or C#, objects may be synchronized not only with signals but directly on conditions. This simplifies the development of concurrent programs.

A fork of Active Oberon is Zonnon.
