Pietro Antonio Rotari (30 September 1707 – 31 August 1762) was an Italian painter of the Baroque period.

Born in Verona, he led a peripatetic career, and died in Saint Petersburg, where he had traveled to paint for the Russian court.

Rotari's works were generally limited to royal portraits held by notables such as emperors and court ladies.

[1] He was much in demand as a portraitist, and painted royal families in Dresden and Saint Petersburg.

He also painted the multi-figured altarpieces of the Four Martyrs (1745) for the church of the Ospedale di San Giacomo in Verona.
