Mtwara Port, Maritime freight terminal in Mtwara, Tanzania.

Mtwara Port is a deep-water harbour on the Indian Ocean in southern Tanzania, managed by the Tanzania Ports Authority. Its quay wall runs 385 metres and handles two ordinary ships plus one ocean-going vessel at once; charted depth at the quay is 9.85 metres. A sheltered inner anchorage 20 metres deep holds six ships of up to 175 metres.

The port was constructed between 1948 and 1954 by the British colonial administration as part of an agricultural development program for the Tanganyika region. The project was part of wider economic plans to boost agricultural exports from the area.

Cashew nuts have long been the port's main export, and in 2021 President Samia Suluhu Hassan ordered that cashews from Mtwara, Lindi and Ruvuma be shipped out through Mtwara. Of Tanzania's 280,000-tonne cashew crop that year, 250,000 tonnes were to leave via this port, putting pressure on container availability.

The port operates around the clock since its natural depth allows large ships to enter and exit at any time without tidal restrictions. Visitors should be aware that as an active cargo terminal, movement may be restricted and proper safety precautions are necessary.

Mtwara Port's inner bay holds a sheltered anchorage 20 metres deep that can take six vessels of up to 175 metres. The charted depth over the deep-water quay reaches -9.5 metres, so ships enter and leave without waiting for the tide. The 385-metre quay handles two ordinary ships and one ocean-going vessel at once.
