[[File:Distributed object communication.png|thumb|Image describes communication between distributed objects residing in different machines.]]

In [[distributed computing]], '''distributed objects''' are objects (in the sense of [[object-oriented programming]]) that are distributed across different [[address space]]s, either in multiple [[computer]]s connected via a [[Computer network|network]] or even in different [[Process (computing)|processes]] on the same computer, but which work together by sharing data and invoking methods. This often involves [[___location transparency]], where remote objects appear the same as local objects. The main method of [[distributed object communication]] is with [[remote method invocation]], generally by message-passing: one object sends a message to another object in a remote machine or process to perform some task. The results are sent back to the calling object. Distributed objects were popular in the late 1990s and early 2000s, but have since fallen out of favor.<ref>[http://martinfowler.com/articles/distributed-objects-microservices.html Microservices and the First Law of Distributed Objects], Martin Fowler, 13 August 2014</ref>

The term may also generally refer to one of the extensions of the basic [[object (computer science)|object]] concept used in the context of distributed computing, such as ''replicated objects'' or ''live distributed objects''.
