Santa Maria della Fiducia is a modern parish church at Via Casilina 1837, in the eastern suburb of Finocchio which is part of the Borghesiana district.
The parish is administered by the Oblati Figli della Madonna del Divino Amore, who are based at the shrine of the same name -Santuario della Madonna del Divino Amore. The dedication is to the Blessed Virgin Mary, under her title of Our Lady of Trust.
The church is one of the more basic designs of Tullio Rossi, and was erected in 1954. The plan is rectangular, with an integral three-sided apse and a narthex. The roofs of all of these are pitched and tiled. The nave has no aisles.
The windowless gabled façade is rendered in a cream colour, and has a stone plaque in its centre with a Papal coat of arms. The large open narthex has three entrance arches, with the piers painted brick-orange, and another arch on each side. The tiling on the sloping narthex roof contains "AM" in darker tiles, which stands for "Ave Maria". The right hand side wall has four round-headed windows, but the left hand one only two because the priests' house abuts on the far side. There is no campanile, but a little gabled bell-cote on the priests' house.
