Unicon is a programming language descended from Icon that offers better access to the operating system as well as support for object oriented programming. Unicon began life as a merger of three popular Icon extensions: an OO preprocessor named Idol, a POSIX filesystem and networking interface, and an ODBC facility. The name is shorthand for "Unified Extended Dialect of Icon."

Unicon is a series of British university-based science fiction conventions, the next of which is named Recombination and is due to be held in New Hall, Cambridge in August 2007.
