Santissimo Crocifisso, Romanesque Revival church in Palmi, Italy.

Santissimo Crocifisso is a church in Palmi with a single rectangular nave ending in a rectangular transept and apse. Its gable facade has a portal framed by two Corinthian pilasters supporting a broken curved pediment, and a semicircular window sits between portal and pediment. The roof is pitched with tiles, and a bell gable rises at the rear.

Construction of the church began in 1537 under Friar Antonio on the remains of an earlier church dedicated to Santa Maria de Caravellis. Over the centuries, the structure underwent multiple transformations that shaped its present appearance.

The church serves as the diocesan shrine of Oppido Mamertina-Palmi and houses a wooden crucifix from the 17th century listed in Italy's Art Objects Inventory. Visitors can observe this carved religious object displayed within the interior layout.

The church stands in the Cittadella district, facing the small piazzetta dell'Annunziata. The interior is a single rectangular nave ending in a raised presbytery, reached by three steps, so the transept and apse sit higher than the seating area. The last full restoration, inside and out, was carried out in 2019 with eight-per-thousand funds.

The church preserves the diocesan shrine of Oppido Mamertina-Palmi, holding numerous relics of saints. Its 17th-century wooden crucifix is listed in the Inventory of Art Objects of Italy. The building survived the earthquakes of 1894 and 1908, unlike the adjoining monastery, which was never rebuilt.
