In computing, CHILL (an acronym for CCITT High Level Language) is a procedural programming language designed for use in telecommunications switches (the hardware used inside telephone exchanges). The language is still used for legacy systems in some telecommunication companies.

The CHILL language is similar in size and complexity to the Ada language. The first specification of the CHILL language was published in 1980, a few years before Ada. CHILL is unusual in that it supports two forms of declaration syntax, one based on Cobol and the other on PL/1.

ITU provides a standard CHILL compiler. A free CHILL compiler was bundled with GCC up to version 2.95, however, was removed from later versions. An object-oriented version, called Object CHILL, was developed as well.[1]

ITU is responsible for the CHILL standard, known as ITU-T Rec. Z.200. The equivalent ISO standard is ISO/IEC 9496:2003. (The text of the two documents is the same). In late 1999 C.C.I.T.T. stopped maintaining the Chill standard.
