Giovanni Porta (c. 1675 – 21 June 1755) was an Italian opera composer.
Porta is believed to have been born in Venice. One of the masters of early 18th-century opera and one of the leading Venetian musicians, Porta made his way from Rome, to Vicenza, to Verona, then London where his opera Numitore was performed in 1720 by the Royal Academy of Music (1719), and eventually back to Venice and Verona, and finally Munich, where he spent the last 18 years of his life.
