1. Walgaš (2nd cent.), son of Naṣrū, at first “lord” (mrʾ), then “king (mlkʾ) of ʿArab(s) (of Hatra)” (inscriptions 140, 193, 286; A. Caquot, Syria 41, 1964, pp. 259-68; B. Aggoula, Syria 52, 1975, pp. 184-85 and 63, 1986, pp. 356, 363, nos. 348, 366). This is probably a dynast of Hatra and its dependent territory under Parthian suzerainty. The new evidence of Hatra inscription no. 348 proves that the Walgaš in question is son of Naṣrū: ṣlmʾ dy Wlgš br Nṣrw mryʾ “statue of Walgaš the lord, son of Naṣrū” (Aggoula, 1986, p. 356). Thus Walgaš must have been the brother of Sanaṭrūq I. Naṣrū ruled in 137/8 and Sanaṭrūq I in 161/2, so Walgaš must have ruled between these two dates (Aggoula, Mélanges de l’Université St. Joseph 17, 1972, pp. 54, 60-61; 1986, p. 363) and was thus a contemporary of the Arsacid King Valagaš/Balāš IV (III). The new evidence disproves earlier attempts to place this Walgaš about 150 or 200, i.e., between Worōd and Naṣrū (J. T. Milik, Recherches d’épigraphie proche-orientale, 1972, p. 364) or before 138 (H. J. W. Drijvers, in ANRW 11/8, pp. 824-25).

2. A prince or king of Hatra, represented dressed in Parthian fashion on a great lintel discovered near the remains of a sanctuary at Hatra, with the inscription nṣr blgš “victory of Walgaš” (Caquot, Syria, 1953, p. 238 no. 33). The identification of this Walgaš with the Arsacid Balāš I suggested by F. Safar (Caquot, p. 239) is based on too scanty evidence.

3. Walgaš son of Walgaš, known from inscription no. 366, engraved on a column commemorating the erection of a statue: ṣlmʾ dy Wlgš br Wlgš “statue of Walgaš, son of Walgaš” (Aggoula, 1986, p. 363). It is not certain that this is the son of King Walgaš above.
