Portacomaro (Piedmontese: Portacomé) is a comune (municipality) in the Province of Asti in the Italian region Piedmont, located about 45 kilometres (28 mi) southeast of Turin and about 7 kilometres (4 mi) northeast of Asti.
Well-preserved apsidal frescos can be found in the romanesque church of St. Peter  (first recorded in 1130 AD). Formerly occupied by a monastic community, the chancel sides are decorated with figures of St. Bernard and St. Sebastian. The central section of tripartite rear wall of the sanctuary (probably the oldest) features a deisis (Crucifixion with Virgin and the beloved disciple, St. John), figures of St. Andrew are to the right, St. Agatha (kneeling) and St Peter to the left.
