What is the Sikh flag flown outside a gurdwara called?

The Nishan Sahib is the Sikh flag flown outside a gurdwara.

It is usually a triangular flag bearing the khanda emblem and is mounted on a tall flagpole, often covered with saffron-colored cloth. The flag identifies a gurdwara as a place of Sikh worship and hospitality. Its visible position outside the building helps visitors locate a gurdwara, including travelers and people seeking food or shelter.

The word nishan means sign or standard, while sahib is an honorific. The flagpole is commonly washed and the cloth replaced in a ceremonial practice known as chola sahib. This maintenance reflects respect for the institution and the community it represents.

The Nishan Sahib should not be confused with the khanda. The khanda is an emblem used on the flag, while Nishan Sahib refers to the flag itself and, in broader usage, the standard associated with a gurdwara. Gurdwaras may display the flag in different local styles, but its public welcoming function is consistent.
