Gurudwara Bangla Sahib is one of the most prominent Sikh gurudwara, or Sikh house of worship, in Delhi, India. It is known for its association with the eighth Sikh Guru, Guru Har Krishan, as well as the pool inside its complex, known as the Sarovar. It was first built as a small temple by Sikh General Sardar Bhagel Singh in 1783.

Gurdwara Bangla Sahib was originally a bungalow belonging to Raja Jai Singh of Amber (Jaipur), an Indian ruler in the seventeenth century, and was known as Jaisinghpura Palace, in Jaisingh Pura.

The eighth Sikh Guru, Guru Har Krishan resided here for a few months as a guest of Raja Jai Singh in 1664. During that time, there was a smallpox and cholera epidemic, and Guru Har Krishan helped the suffering by giving aid and fresh water from the well at this house.  A small tank was later constructed by Raja Jai Singh over the well, its water is now revered as having healing properties.
