Farn-Sasan was the last king of the Indo-Parthian Kingdom, ruling the region of Sakastan approximately from 210 to 226.

He was defeated in 226 by the Sasanian ruler Ardashir I (r. 224–242), which marked the end of Indo-Parthian rule.

"[2][a] With this inscription, Farn-Sasan tried to legitimize his rule by linking himself with his great-grandfather Sanabares, who was the last prominent Indo-Parthian king.

[5][1] Neither Adur-Sasan nor Tirdat is known to have ruled, which implies that Farn-Sasan was seemingly from a cadet branch of the dynasty.

[7] It is uncertain if Farn-Sasan copied the iconography of Ardashir I's reverse coins, or vice versa.
