Sikhism in Sindh

Sikhism in Sindh, or Sindhi Sikhs, is a minor religious affiliation, adhered to by 5,182 people or around 0.01% of the total population as per 2023 Pakistani census. The religion has a long history in Sindh, with the Udasi and Nanakpanthi sects playing a prominent role. In recent years, mainstream Khalsa Sikhism has made inroads. Local Sindhi beliefs and practices often blur the line between Hinduism and Sikhism, an example of religious syncretism. Sikhism was popularized in Sindh by the missionary work of Nanakpanthi traders and Udasi saints. Nanakpanthi and Udasi are both Sikh sects; a major difference is that Udasis adopt life-long celibacy, whilst Nanakpanthis marry and have children.

In the Sindh province of Pakistan, the Sikh marriages are registered under the Sindh Hindu Marriage Act of 2016. Sindhis (mostly those settled in Gujarat) are one of the largest groups to visit Kartarpur Sahib. Since 1947, a sizeable portation of Sindhi Sikhs migrated to the Republic of India, whilst some remained behind in Pakistan.

Sindhi Sikhs internally categorize themselves into different groups, such as Bandai, Nawabshahi, or Naichan, among others.
