NN, Nn, or nn may refer to:
nn ("No News is Good News") is a Unix text-based news client, which is a client software program for accessing Usenet servers.
nn was originally written in 1984 by Kim F. Storm to provide an alternative more user-friendly way to access Usenet than the existing newsreaders. nn is currently at version 6.7.3, and is now maintained by Michael T. Pins.
nn was known for its mode separation between choosing and reading articles. Threads were presented for reading or skipping, and once all choices in a newsgroup were made, the user continued on to reading the selected articles.
NN is a 2014 Peruvian drama film directed by Héctor Gálvez. The film was selected as the Peruvian entry for the Best Foreign Language Film at the 88th Academy Awards but it was not nominated.
