The Rabatak Inscription is a stone inscribed with text written in the Bactrian language and Greek script, found in 1993 at Rabatak, near Surkh Kotal in Afghanistan. The inscription relates to the rule of the Kushan emperor Kanishka, and gives remarkable clues on the genealogy of the Kushan dynasty. It dates to the 2nd century CE.

Surkh Kotal (Persian: چشمه شیر Chashma-i Shir; also called Sar-i Chashma, is an ancient archaeological site located in the southern part of the region of Bactria, about 18 kilometres (11 mi) north of the city of Puli Khumri, the capital of Baghlan Province of Afghanistan. It is the location of monumental constructions made during the rule of the Kushans. Huge temples, statues of Kushan rulers and the Surkh Kotal inscription, which revealed part of the chronology of early Kushan emperors (also called Great Gara) were all found there. The Rabatak inscription which gives remarkable clues on the genealogy of the Kushan dynasty was also found in the Robatak village just outside the site.
The site of Surkh Kotal, excavated between 1952 and 1966 by Prof. Schlumberger of the Délégation Archéologique Française en Afghanistan, is the main site excavated of the Kushan Empire. Some of the site's sculptures were transferred to the National Museum of Afghanistan (also known as the 'Kabul Museum'), the rest of the site was completely looted during the Afghan Civil War. The most famous artifacts of this site are the Surkh Kotal inscriptions, the statue of King Kanishka and the fire altar. The statue of the king was destroyed during the Taliban wave of iconoclasm in February–March 2001, but has been restored by French conservationists. The three artifacts are currently on display in the Afghan National Museum.
