R. Aaron b. Hayyim Abraham Ha'Kohen Perahyah (1627?–1697), rabbi and halakhic authority of Salonika. Perahyah was born in Salonika and studied there under R. Asher b. Ardut ha-Kohen, R. Hasdai ha-Kohen Perahyah, and R. Hayyim Shabbetai. In 1689 he succeeded R. Elijah Covo as chief rabbi of Salonika. He was regarded as an important posek among Salonika rabbis. His other works are: Pirhei Kehunnah (Amsterdam 1709), novellae to the tractates Bava Kamma, Bava Mezia, Ketubbot, Gittin, Avodah Zarah, and Kiddushin; Bigdei Kehunnah (Saloniki 1753), eulogies and homilies; and Zikhron Devarim (ibid., 1758), source references for the Arba'ah Turim of Jacob b. Asher. In his Parah Matteh Aharon he mentions another work, on Alfasi, of which nothing is known.
