Helvesiek is a municipality in the district of Rotenburg, in Lower Saxony, Germany.

Helvesiek belonged to the Prince-Bishopric of Verden, established in 1180.

In 1648 the Prince-Bishopric was transformed into the Principality of Verden, which was first ruled in personal union by the Swedish Crown - interrupted by a Danish occupation (1712-1715) - and from 1715 on by the Hanoverian Crown.

In 1813 the Principality was restored to the Electorate of Hanover, which - after its upgrade to the Kingdom of Hanover in 1814 - incorporated the Principality in a real union and the Princely territory, including Helvesiek, became part of the new Stade Region, established in 1823.
