The Sambirano is a river of northwestern Madagascar in the region of Diana. It has its sources at the Maromokotra peak and flows through the Tsaratanana Reserve to the Indian Ocean. Its delta occupies 250 km{{sup|2}}.

The ecosystem of the river, mainly forests and brushland, has many indigenous species, such as the Sambirano mouse lemur and Sambirano woolly lemur.{{cite book|last1=Kennerley|first1=Peter|last2=Pearson|first2=David|title=Reed and Bush Warblers|url=https://books.google.com/books?id=-EbjzHc_T0UC&pg=PA528|accessdate=8 January 2013|date=15 September 2010|publisher=A&C Black|isbn=978-0-7136-6022-7|page=528}}

The Madagascar dry deciduous forests occupy much of the river basin, although mangroves are evident at parts of the coastal fringe.World Wildlife Fund, C. Michael Hogan. 2010.

The valley of the Sambirano is the main cocoa producing area of Madagascar. 60% (or 7500 to 10 000 tons yearly) provide from this area. There is an unpaved piste from Ambanja to Marovato, via Benavony, Ambodimanga Ramena, Bemaneviky Ouest, Maevatanana that is hardly practicable.[https://documents1.worldbank.org/curated/en/165771531380104866/pdf/PAR-Piste-Haut-Sambirano-Final.pdf PAR-Piste-Haut-Sambirano-Final.pdf]

Most of the exported cocoa is therefore transported with boats on the Sambirano river to Ambanja and the National road 6
