In [[computer science]], in an object-oriented program, groups of objects form a network through their relationships with each other—either through a direct reference to another object or through a chain of intermediate references. These groups of objects are referred to as object graphs.

An '''object graph''' is a view of an [[object system]] at a particular point in time. Whereas a normal [[data model]] such as a [[Unified Modeling Language|UML]] [[Classclass diagram]] details the relationships between classes, the object graph relates their instances. [[Object diagram]]s are subsets of the overall object graph.

Object-oriented applications contain complex webs of interrelated objects. Objects are linked to each other by one object either owning or containing another object or holding a reference to another object. This web of objects is called an object graph and it is the more abstract structure that can be used in discussing an application's state.
