Jamholt Region was an area of land on the planet Acamar III. This land was claimed by the Clan Tralesta and was bordered by the Jimbern Regions.

In 2286, the Clan Lornak quickly overwhelmed the Tralesta police and militia forces stationed in this region. As the last remnants of these forces were being destroyed, Mesabb mobilized the villagers in a futile attempt at diverting the Lornack attack. The attempt failed with two hundred deaths recorded in the first twelve hours.

In 2366, this region was mentioned in the history file of the Tralesta Massacre, which was accessible to the crew of the USS Enterprise-D via the Acamarian planetary database. (TNG: "The Vengeance Factor", okudagram)

This region was only mentioned in writing.
