Santi Demetrio e Bonifacio is a former-Roman Catholic church located on Piazzetta Teodoro Monticelli, in central Naples, Italy.
The site had once held a small chapel or oratory dedicated to San Demetrio.
The main altarpiece, on a polychrome marble altar, depicts a Madonna with Saints Demetrio and Bonifacio by Nicola Maria Rossi.
The lateral altars have canvases depicting a Madonna and child with Saints Paul the Hermit, Leonard Abbot, and Gerolamo Emiliani by Antonio Romeo, and a Madonna and Child with St Gerolamo Emiliani by Gennaro Gamba.
[1] With the 19th-century suppression of orders, the church fell to the jurisdiction of the Archbishop, then a Congregation of Studies (1821), and a Arch-Confraternity of the Visitation (1907).
