Nord-Rana (historically: Mo) is a former municipality in Nordland county, Norway.

The administrative centre was the village of Ytteren, just north of the town of Mo i Rana.

On 1 January 1923, the village of Mo was designated as a ladested and so it was separated from the rest of the municipality to become a town-municipality of its own.

The name of the river is probably derived from the word raðr which means "quick", "fast", or "rapid".

[11][12] The highest point in the municipality was the 1,589.26-metre (5,214.1 ft) tall mountain Snøtinden.

The municipal council (Herredsstyre) of Nord-Rana was made up of 35 representatives that were elected to four year terms.
