Vicia narbonensis, called Narbon bean, Narbon vetch, Narbonne vetch and moor's pea, is a widely distributed species of flowering plant in the family Fabaceae. It is native to Madeira and the Mediterranean countries through to Central Asia and the western Himalayas, and has been introduced to central and eastern Europe, and scattered other locations. It has some palatability issues, but has potential as a green manure and forage crop, and for its beans. It is the namesake of the Vicia narbonensis species complex.
