Gurdwara Shahid Ganj Singh Singhania is a historic Sikh shrine in Lahore associated with the martyrdom of Sikh men, women and children during the eighteenth century. The site stands in the historic Shahidganj area of Naulakha Bazaar, opposite Gurdwara Shaheed Bhai Taru Singh, and is remembered as one of the major places of Sikh persecution and sacrifice in Lahore.

According to SGPC records and Sikh historical accounts, large numbers of Sikhs were imprisoned, brought to this area and executed during periods of severe persecution under eighteenth-century Punjab governors, including Mir Mannu. Sikh women were also confined and forced to perform hard labour, including grinding grain in the basement of the site, while enduring extreme suffering. Because of the prominent remembrance of these women, the shrine came to be known as Shahid Ganj Singhnian.

The site later developed into a Gurdwara and became an important place of remembrance within the Sikh community. During the Sikh Empire, Maharaja Ranjit Singh is recorded as having visited the shrine regularly and granted land for its maintenance. The management of the Gurdwara was transferred to the Shiromani Gurdwara Parbandhak Committee in 1934, while after Partition the property came under the management of the relevant Pakistani trust authorities.
