'''Nested Context Language''' (NCL) is a declarative authoring language for [[Hypermedia|hypermedia]] documents.

NCL is an [[XML]] application language, which provides several facilities for authoring a complete hypermedia document with synchronization relationships among its components. Among its main facilities, it treats hypermedia relations as first-class entities through the definition of hypermedia connectors, and it can specify arbitrary semantics for a hypermedia composition using the concept of composite templates.

Following others XML standards, NCL is specified by a modular approach. NCL modules can be added to standard web languages, such as [[XLink]] and [[Synchronized Multimedia Integration Language|SMIL]].

NCL was initially designed for the Web environment, but currently it is included as the declarative language of the Japanese-Brazilian [[ISDB-Tb|ISDB-Tb]] (International Standard for Digital Broadcasting) terrestrial DTV (digital TV) middleware (named [[Ginga (SBTVD Middleware)|Ginga]]). It is also the first standardized technology of the [[ITU-T|ITU-T]] multimedia application framework series of specifications for [[IPTV|IPTV]] services.
