Kharosthi script (Gāndhārī: 𐨑𐨪𐨆𐨮𐨿𐨛𐨁𐨌𐨫𐨁𐨤𐨁, romanized: kharoṣṭhī lipi), also known as the Gandhari script (𐨒𐨌𐨣𐨿𐨢𐨌𐨪𐨁𐨌𐨫𐨁𐨤𐨁, gāndhārī lipi), was an ancient Indian script used by various peoples from the north-western outskirts of the Indian subcontinent (present-day Pakistan) to Central Asia via Afghanistan. An abugida, it was introduced by the middle of the 3rd century BCE, possibly during the 4th century BCE, and remained in use until it died out in its homeland around the 3rd century CE.

It was also in use in Bactria, the Kushan Empire, Sogdia, and along the Silk Road. There is some evidence it may have survived until the 7th century in Khotan and Niya, both cities in East Turkestan.
