Sarhang is a title and/or military rank of Iranian origin, a compound of sar ("head, chief") and hang ("an army division").

In modern usage in Iran, sarhang (Persian: سرهنگ) is the equivalent of 'General officer' or simply 'General,' the highest rank in the military.

The origin of the title sarhang may date back at least to the Parthian period.

In the medieval period, sarhang has been defined as "a heroic man, a brave fighter, a night-guard".

According to Bosworth, sarhangs were separate from ayyars, and were probably fighters with outstanding leadership or fighting qualities that were recruited from the latter.
