Vittorio Bigari (1692 – 1776) was an Italian painter of the late-Baroque period.
He was active in his native Bologna, where he was a pupil of Antonio Dardani. He painted frescoes in the Basilica of San Domenico in Bologna, as well as the cupola of the church of the Madonna della Guardia, and the gallery of the Ranuzzi Palace in Bologna. He also painted in the Palazzo Aldrovandi. He also painted for the Madonna del Soccorso. The Pinacoteca Nazionale di Bologna includes two paintings by him: Convito di Baldassarre and Salomone incensa gli idoli. A follower of Bigari was Francesco Gadi.
