Netscape Communicator was the proper brand name of an Internet software applications suite originally produced by Netscape Communications Corporation in the late 1990s. This suite included the Netscape Navigator web browser (its most prominent component) along with applications for email, Usenet news, and other miscellany.

Because none of the applications besides Navigator were popular on their own, and because Netscape never produced any other desktop software that approached the popularity of Navigator, people would often refer to both the Communicator suite and Navigator as simply "Netscape".
