Rakhsh (in Persian: رخش, meaning "luminous") is a wondrous stallion -the brave and faithful steed of the preeminent hero Rostam in the Persian national epic, Shahnameh by the poet Ferdowsi.

The color of Rakhsh is described as "rose leaves that have been scattered upon a saffron ground" and it is first noticed by Rostam amongst the herds of horses brought over from Zabulistan and Kabul.

In this first encounter Rakhsh is described as a mighty colt with the chest and shoulders of a lion and it appears to have the strength of an elephant.

Due to divine favor protecting Rostam, Rakhsh lives an unusually long life.

Raḵšā (Rakhsha) in Aramaic means horse.
