Wahrez (born Boe or Bōē) was a Sasanian general of Daylamite origin, first mentioned in the prelude to the Iberian War and then during the Aksumite–Persian wars.
He was born Boe (Middle Persian: Bōē, بویه Bōyah/Büyah), which is Hellenized as Boes.
He is better known by his title of Wahrīz (Middle Persian: wḥlyč; in بهريز Bahrīz; in Greek: Οὐαριζης Ouarizes, in Vaphrizes; Modern Persian: وهرز).
Wahrez is first mentioned in the prelude to the Iberian War, where he was sent by the Sasanian king (shah) Kavadh I (r. 498–531) to Caucasian Iberia in order to subdue a revolt under Gurgen.
During the reign of Kavadh's son, Khosrau I, the Yemenites had requested assistance against Axum dominance, who had occupied large parts of the country. Sayf ibn Dhi-Yazan, the son of Dhu Yazan, went to Khosrau and offered him all of Yemen if his army would defeat the Axumites.

Khosrau then sent Wahrez and his son Nawzadh to Yemen at the head of a small expeditionary force, numbering around 800, of low-ranking Azatan (Azadan) nobility. According to other traditions, it consisted of prisoners that were sentenced to death, while according to another version, the force also included (or entirely consisted of) warriors from Daylam and nearby regions. only two out of eight ships (i.e. 600 men) safely reached the Yemeni coast, who joined the local Himyarite allies and invaded the combined forces of the Aksumites, their Himyarite allies, and certain "Bedouins". During the invasion, Nawzadh was killed, which made Wahrez furious at Masruq ibn Abraha, the Axumite ruler of Yemen. Wahrez then met Masruq in battle and killed him with an arrow, which made the Axumites flee. He then conquered Sana'a, where he is known to have refused to lower his banner to enter via the city gate. Wahrez then restored Sayf ibn Dhi-Yazan to his throne as a vassal of the Sasanian Empire.
