Santa Marcella, Modern church in Ostiense district, Rome, Italy.

Santa Marcella is a church in Rome's Ostiense district, built between 1958 and 1969 to a design by Leonardo Del Bufalo. Its irregular hexagonal plan has longer side walls and shorter entrance and altar walls, all in exposed brick. A tall, narrow reinforced-concrete bell tower with the same hexagonal plan stands to the right of the entrance.

The church was officially established as a parish in 1958 through a decree issued by Cardinal Clemente Micara. This creation reflected the growth and development of Rome's neighborhoods in the post-war period.

The church is dedicated to Marcella of Rome, a Roman widow who converted to Christianity and followed the teachings of Saint Jerome; she is not a martyr. On the counter-facade, Dilvo Lotti's fresco shows Christian symbols (loaves, fish, anchor) and episodes from the Gospels.

The church is located near Ostiense train station, making it accessible by public transportation from the city center. Visitors should check service times before arriving, and detailed information about opening hours is available upon request.

The Mascioni organ, opus 962, was built in 1973 and sits on the matroneum above the entrance wall. Its console stands on the nave floor, with two 61-note manuals and a 32-note concave-radial pedalboard, and electric transmission. The pipes are held in a plain geometric case, with principal pipes set outside in a palisade arrangement with mitered mouths.
