Gnus (/ɡəˈnuːz, ˈɡnuːz/), or Gnus Network User Services, is a message reader which is part of GNU Emacs. It supports reading and composing both e-mail and news and can also act as an RSS reader, web processor, and directory browser for both local and remote filesystems.

Gnus blurs the distinction between news and e-mail, treating them both as "articles" that come from different sources. News articles are kept separate by group, and e-mail can be split into arbitrary groups, similar to folders in other mail readers. In addition, Gnus is able to use a number of web-based sources as inputs for its groups.
