Jamo (Jāmo), also spelled Jamun or Jamon, is a village and community development block headquarters in Gauriganj tehsil of Amethi district, Uttar Pradesh, India. As of 2011, it had a population of 6,734 people, in 1,182 households. It was historically the capital of the pargana of Gaura Jamun. It is located at the intersection of four minor district roads, some of which are prone to flooding during the rainy season.

Jamo was historically the capital of the pargana called Gaura Jamun. It was also the seat of a taluqdari estate held by a branch of the Kanhpuria. The Jamo branch originated in a partition of lands among the four sons of one Balbhaddar Singh; the other three branches were Katari, Bhawan-Shahpur, and Raisi. The Baraulia taluqa was later formed as a junior branch of the Jamo taluqa.

At the turn of the 20th century, Jamo was described as consisting of a built-up block surrounded by a moat and 21 dependant hamlets. It had an aided school, maintained by the taluqdar and with only a few students. It had a village bank. The population as of 1901 was 1,967 people, and the majority of them were Brahmins, including the leading family of some prosperous moneylenders who owned several large houses in town. The village was described as good for agriculture with many shallow depressions providing plenty of water for irrigation. At that time, the Jamo taluqdar Mahabir Bakhsh Singh held 17 villages, all in the pargana of Gaura Jamun, but he was severely in debt and the estate was in effect mortgaged to a nobleman from Rewah State.

The 1951 census recorded Jamo as comprising 20 hamlets, with a total population of 2,170 people (1,065 male and 1,105 female), in 468 households and 447 physical houses.

The village had a district board-run primary school with 124 students in attendance as of 1 January 1951.

The area of the village was given as 1,525 acres and it had a post office at that point, as well as a government-run dispensary with 2 male and 2 female beds.
