3HO (Healthy, Happy, Holy Organization) (est. 1969) is a non-profit organization dedicated to sharing the teachings of Kundalini Yoga as taught by Yogi Bhajan, founder of the group.

The stated mission of 3HO is to "share the lifestyle, yoga and meditation practices of Kundalini Yoga," claimed by its practitioners to be the most powerful and accessible form of yoga. This yogic lifestyle practice includes Kundalini yoga, meditation, diet, clean living, and yogic philosophy. The 3HO Foundation serves as the central organization for a global community of yoga teachers, students, and everyday people who practice and share the Kundalini yoga and lifestyle teachings of Yogi Bhajan. Their goal—centered and grounded in a philosophy of compassion and kindness—is that they may serve, inspire, and empower humanity to be healthy, happy, and holy.

3HO describes itself as a spiritual community welcoming of all religions and lifestyles. Teaching Kundalini Yoga does not require belief in Sikhism, however many followers of Harbhajan Singh Yogi choose to follow a variation of the Sikh way of life, as many traditional Sikhs do not approve of the practice of yoga. The associated Sikh Dharma movement, based in Española, New Mexico, considers itself a Sikh sangat, and its followers observe the five K's. Men and women each wear large white dastaar. The movement's gender politics are egalitarian.
