Nicolas Vallet (born around 1583 in Corbeny near Laon; died after 1642 in Amsterdam(?)) was a Dutch lute composer of French descent.
Vallet, a Huguenot, was forced to flee France for the Netherlands. In Amsterdam, he worked as an independent musician, lute teacher, and owner of a dance school. His major work, „Le Secret des Muses,“ contains compositions and arrangements for the ten-course Renaissance lute. It was published in two parts in 1615 and 1616. He was one of the last composers for this instrument before it was superseded by the Baroque lute. He also composed the 21 Psalms of David in 1615 and the Regia Pietas for voice and lute in 1622.
