The church of the Santissima Trinità alla Cesarea (or Santa Maria del Rimedio a Salvator Rosa) is a Baroque-style church, located in Piazetta Trinità alla Cesarea, in central Naples, Italy.
The church and the convent were built by friars for the Redemption of Captives of the Order of Santa Maria della Mercede. They sited it at the site by buying in the 17th century the palace of Cardinal Belmosto. In this era, noble families were abandoning the low-lying neighborhoods of Naples for higher ground. The monastery later passed on to the Trinitarians, giving its present name. In 1809, the monastery was suppressed. The Irpinia earthquake of 1980, caused the church to be closed. Only in 2008 was the ceiling resealed. The facade is in a dilapidated state. The interior has a frescoed ceiling.
