The Kandahar Bilingual Rock Inscription, also known as the Kandahar Edict of Ashoka and less commonly as the Chehel Zina Edict, is an inscription in the Greek and Aramaic languages that dates back to 260 BCE and was carved by the Mauryan emperor Ashoka at Chehel Zina, a mountainous outcrop near Kandahar, Afghanistan. It is among the earliest-known edicts of Ashoka, having been inscribed around the 8th year of his reign, and precedes all of his other inscriptions, including the Minor Rock Edicts and Barabar Caves in India and the Major Rock Edicts. This early inscription was written exclusively in the Greek and Aramaic languages. It was discovered below a 1-metre (3.3 ft) layer of rubble in 1958 during an excavation project around Kandahar, and is designated as KAI 279.

The Edicts of Ashoka are a collection of more than thirty inscriptions on the Pillars of Ashoka, as well as boulders and cave walls, attributed to Emperor Ashoka of the Maurya Empire who reigned the Indian subcontinent from 268 BCE to 232 BCE. Ashoka used the expression Dhaṃma Lipi to describe his own Edicts. These inscriptions were dispersed throughout the areas of modern-day Bangladesh, India, Nepal, Afghanistan and Pakistan, and provide the first tangible evidence of Buddhism. The edicts describe in detail Ashoka's view on dhamma, an earnest attempt to solve some of the problems that a complex society faced. According to the edicts, the extent of Buddhist proselytism during this period reached as far as the Mediterranean, and many Buddhist monuments were created.
