Sant'Ambrogio ad Nemus is a Baroque style, Roman Catholic convent in Milan, Italy. The convent is no longer functioning, but the oratory or church remains. While the present church dates to a reconstruction begun in 1635, the site was associated with the founding of monasticism by Saint Ambrose. The term ad Nemus referred to a forest outside of the medieval walls. The walls were frescoed in the 17th century. Above the entrance of the church are frescoes by the painter Cocchi.
