Flavius Latinus (died 115) was a Christian martyr of the persecutions of Trajan.
He is said to be the third bishop of Brescia, successor to Saint Viator. This tradition is, however, questioned. Viator of Bergamo is a much later figure, and the reference to his earlier being a bishop of Brescia is doubted. The historical list of bishops of Brescia is not established so far back as the early persecutions in the 2nd century.
He was a Catholic and an Orthodox saint, feast day March 24.
