Giovanni Mossi (c. 1680 in Rome – 1742 in Rome) was an Italian baroque composer.
Many of the details of his life appear to be lost. Mossi was active in Rome around 1700 and is grouped stylistically with the "Roman school" of the period, along with others such as
Giuseppe Valentini. From what can be observed in his extant works, he appears to have been a skilled and innovative composer. He is most known for his collection of violin sonatas.
