NDR Fernsehen is a German free-to-air regional television channel targeting northern Germany, specifically the states of Schleswig-Holstein, Lower Saxony, Mecklenburg-Vorpommern, Hamburg and Bremen.

It is broadcast by both Norddeutscher Rundfunk (NDR) and Radio Bremen, although the former provides most of the output as they are bigger than the latter.

It started broadcasting on 4 January 1965 as the common channel of NDR, Radio Bremen and Sender Freies Berlin (SFB).

In 1992, the stations broadcast area changed as Mecklenburg-Vorpommern was added to NDR after the German reunification and SFB left the N3 cooperation in October to start its own channel, B1 (now rbb Fernsehen).

The channel was initially only available terrestrially in its designated area, but since it became available on satellite and cable television it is available nationally.
