Gahmar is a village in India, located near the Ganges river in the Ghazipur district in the state of Uttar Pradesh.

[6] Gahmar was settled by Sakarwar Rajputs, the descendants of Dham Deo Misir who came from the vicinity of Fatehpur Sikri after Babur captured it in 1527 AD.

After moving east from Fatehpur Sikri, initially, both of them settled in Sakradih, but due to floods, Dham Deo migrated to Maa Kamakhya Dham near Gahmar and Kam Deo settled in Reotipur.

One of Roop Ram's son, Sainu Mal Rao and his descendants settled largely in Gahmar.

Gahmar is situated on NH-124C which is connected to district headquarters Ghazipur, about 35 Km.
