Gurdwara Bangla Sahib () is one of the most prominent Sikh gurdwaras, or Sikh house of worship, in Delhi, India, and known for its association with the eighth Sikh Guru, Guru Har Krishan, as well as the holy pond inside its complex, known as the "Sarovar." Originally a bungalow of Raja Jai Singh I of Amber, it was rebuilt as a small shrine by Sikh General Sardar Baghel Singh in 1783. In the same year, there was reconstruction of nine Sikh shrines in Delhi.
It is situated near Connaught Place, New Delhi on Baba Kharak Singh Marg and it is instantly recognisable by its golden dome and tall flagpole.

Gurdwara Bangla Sahib was originally a bungalow belonging to Raja Jai Singh, a Hindu Rajput ruler in the seventeenth century. Guru Har Krishan stayed at the bungalow after being invited to Delhi by Jai Singh. The gurdwara and its Sarovar are now a place of great reverence for Sikhs, and a place for special congregation on birth anniversary of Guru Har Krishan. The sarovar measures 225 by 235 feet with an 18 foot wide parkarma and a 12 foot wide veranda along its three sides.
The Delhi Sikh Gurdwara Management Committee operates a hospital in the sublevels of the structure. Also connected to the site is a Khalsa Girls School and an art-gallery and museum named after Baghel Singh.
