Jean-Pierre Guignon, né Giovanni Pietro Ghignone (10 February 1702 – 30 January 1774) was an 18th-century Franco-Italian composer and violinist.
Born in Turin, Guignon was the son of a merchant from this city and a disciple of Giovanni Battista Somis.
His merits as a violinist earned him the nickname of "Roy des violonistes", i.e. director of the ménestrandise [fr], a title which was then in disuse and which would be deleted after him.
The performances of his own concertos and those of the Venetian master Antonio Vivaldi at the Concert Spirituel were received with great success.
In 1741, king Louis XV granted him French nationality and the title of "Royal Master of the Menetriers".
