Santa Felicita (Church of St Felicity) is a church in Florence, Italy, probably the oldest in the city after San Lorenzo. In the 2nd century, Syrian Greek merchants settled in the area south of the Arno and are thought to have brought Christianity to the region. The first church on the site was probably built in the late 4th century or early 5th century and was dedicated to Saint Felicity of Rome. A new church was built in the 11th century and the current church largely dates from 1736–1739, under design by Ferdinando Ruggieri, who turned it into a one nave edifice.
