Sant Baba Nand Singh (8 November 1870 – 29 August 1943) was a Sikh Saint.

It is reported that he displayed a proclivity for meditation from a young age, once being found doing so while sitting at the edge of a well in the middle of the night.

[3] Nand Singh left his house to do sewa at Gurdwara Sahib in Firozpur.

The food (langar) was provided by nearby villagers, a practice which is in place to this day.

[3][5] Nand Singh left his bodily form at Nanaksar in Punjab which is now recognized as the central dera although his devotees have established Gurudwaras under the name of Nanaksar across Punjab, Haryana, Uttarakhand, and Canada.
