The Blue Mosque, also known as the Shrine of Hazrat Ali, is a mosque located in the center of Mazar-i-Sharif in the northern Balkh Province of Afghanistan.

The site is also where many pilgrims annually celebrate Nowruz (Persian New Year). At the annual Jahenda Bala ceremony, a holy flag is raised in honour of Hazrat Ali. People touch the flag for luck in the New Year.
