The Minho (/ˈmiːn.juː/ MEEN-yoo; Portuguese: [ˈmiɲu]) or Miño (/ˈmiːnjoʊ/ MEEN-yoh; Spanish: [ˈmiɲo] ⓘ; Galician: [ˈmiɲʊ]; Proto-Celtic: *Miniu) is the longest river in the autonomous community of Galicia in Spain, with a length of 340 kilometres (210 mi).

[citation needed] The source of the Minho lies north of Lugo in Galicia, in a place called Pedregal de Irimia.

About 20 kilometres (12 mi) north of Ourense at Os Peares, the Minho, with a discharge of 102 m3/s, receives the waters of its main tributary, the Sil, with 184 m3/s.

The valley is a lush, green agricultural area where the land is used to produce corn, potatoes, cabbage, even kiwi fruit, or just grass, depending on the time of year, and everywhere, edging the fields, rivers, and gardens, wherever there is space, are the vines that produce the light, slightly sparkling "Vinho Verde" and the Ribeiro wine, both peculiar to this area.

The first 64 kilometres (40 mi) cross the plateau of Lugo (Terrachá), a peneplain whose elevation ranges from 450 to 650 metres (1,480 to 2,130 ft) above the sea level.
