'''GNU Ubiquitous Intelligent Language for Extensions'''<ref name="About Guile" /> ('''GNU Guile''') is the preferred [[extension language]] system for the [[GNU Project]]<ref name="GNU coding standards" /> and features an implementation of the programming language [[Scheme (programming language)|Scheme]]. Its first version was released in 1993.<ref name=blandy1997 />  In addition to large parts of Scheme standards, [[#Guile Scheme|Guile Scheme]] includes modularized extensions for many different programming tasks.<ref name="Manual, API Reference" /><ref name="Manual, Guile Modules" />

For extending programs, Guile offers ''libguile'' which allows the language to be embedded in other programs, and integrated closely through the [[C (programming language)|C]] language [[application programming interface]] (API); similarly, new [[data type]]s and [[subroutine]]s defined through the C API can be made available as extensions to Guile.<ref name="Blandy quote C integration" />

Guile is used in many programs under the [[GNU project]] umbrella ([[GNU Debugger |GDB]], [[GNU Make| Make]], [[GNU Guix | Guix]], [[GNU TeXmacs]], [[GnuCash]], [[LilyPond]], [https://github.com/lepton-eda/lepton-eda Lepton-EDA]...)<ref name="Applications using Guile"/> but it also sees use outside of that, for example in [https://github.com/schism-lang/schism Google's schism].
