Hassel is a village administered by the Lower Saxon town of Bergen in the northern part of Celle district on the Lüneburg Heath in North Germany.

It lies about 11 kilometres (6.8 mi) south of Bergen on the B 3 federal road in the glacial valley of the River Örtze.

It is not clear when the village of Hassel first came into being, but what is certain is that the first settlements appeared between Krähenberg and Ostermoor on the slopes of the glacial valley of the Örtze.

The amount of land around the individual villages which was allocated to them was based on the grazing rights they had held in the past.

Farms to which the so-called manorial rights applied had been hitherto obliged to give numerous services and make frequent payments to the manor.

Since the 14th century Winsen was recorded as having a vogtei's office, the lowest level of administration and justice, which was presided over by a ducal vogt.

Matters of importance that only affected Hassel were discussed and decided by the Realgemeinde, i.e. the farm owners who had common land rights.
