A foundational structure in semantic web technologies that allows individual RDF graphs to be identified distinctly. It’s a key concept of Semantic Web architecture in which a set of RDF statements (a graph) are identified using a Uniform Resource Identifier (URI).

For example, a Named Graph could represent a specific dataset or collection of data, such as a list of movie reviews. The graph would be identified by a unique URI, such as http://data.semanticweb.com/movies/, and would contain RDF statements representing the various aspects of the movie data, such as titles, directors, genres, and ratings.
