There are more than 27 million Sikhs around the world, which makes Sikhi (also known as Sikhism) the fifth-largest major world religion. Yet the Sikh tradition remains largely unknown to the global community – no other religion of its magnitude is as misunderstood as Sikhi.

The Sikh religion has been underrepresented and misrepresented in the popular media, and these problems have contributed to the serious challenges that Sikhs experience today, including negative stereotypes, discriminatory policies, and violent hate crimes.

This guide — a collaboration between the Sikh Coalition and ReligionLink and updated in 2025 — provides information on the Sikh tradition in order to facilitate better understanding of Sikhs and Sikhi.
