Andronicus, Probus and Tarachus (Greek: Άνδρόνικος, Πρόβος καί Ταράχος) were martyrs of the Diocletian persecution (about 304 AD).

According to the Acts, Tarachus (c. 239- 304), a Roman who was a native of Claudiopolis in Isauria and a former soldier,[2] the plebeian Probus of Side in Pamphylia, and the patrician Andronicus, who belonged to a prominent family of Ephesus, were tried by the governor Numerian Maximus and horribly tortured three times in various cities, including Tarsus, Mopsuestia, and Anazarbus of Cilicia.

Probus was thrashed with whips, his feet were burned with red hot irons, his back and sides were pierced with heated spits; finally he also was cut up with knives.

Three men, named Marcian, Felix, and Verus, witnessed their martyrdom and added an epilogue to the saints' Acts.

Harnack, however, expressed doubts as to the genuineness of the account, and Hippolyte Delehaye puts the martyrdom in the class of legends of martyrs that he calls "historical romances".
