Dargaz County (Persian: شهرستان درگز) is in Razavi Khorasan province, Iran.

[2] Its prestigious ancient name of Abivard (the Apavartene in the works of the ancient geographers, Ptolemy and Strabo) was changed just a few years ago, believing wrongly that it is a later Arabic name.

[citation needed] Apavarta simply meant "rosewater" in Parthian and Old Persian.
