Offen 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.

Offen lies about 5.6 kilometres (3.5 mi) south of Bergen on the B 3 federal road and has 1,019 inhabitants (2019).

There was another significant increase in the population to 348 in 1948 after the Second World War, mainly as a result of the influx of refugees.

In the last decade the local British garrison had new housing estates built within the village for its families.
