Giacomo Abbondo (27 August 1720 – 9 February 1788) was an Italian Roman Catholic priest who hailed from Vercelli.
Abbondo served as a pastor and provost in his home town of Tronzano where he administered to the people while proclaiming the message of the Gospel and bringing the sacraments to his parishioners.
Pope Francis proclaimed him to be Venerable in 2014 and approved a miracle needed for his beatification in 2015.
The beatification was celebrated in Vercelli on 11 June 2016; Cardinal Angelo Amato led the celebration on behalf of the pope.
