Santi Mario, Marta, Audiface e Abaco is a 21st century parish church at Via Trino in the suburb of Valle Santa, itself in the zone of Casalotti.
The dedication is to SS Marius, Martha, Audifax and Abachum.
The church is in the municipality of Rome, but belongs to the diocese of Porto Santa Rufina.
The project to build a new church for the suburb was begun in 2019, and was due to be completed in 2022.
It will replace Santa Maria di Loreto a Boccea, and will be part of a sports and social complex.
