A constitutional referendum was held in the Batavian Republic on 6 October 1801.
After a previous referendum in 1798 resulted in a new constitution being approved, the French were not satisfied with this constitution, and under their influence a new constitution was written.
In 1801, a referendum was held about the new constitution.
Non-voters were counted as if they agreed to the new constitution, and the constitution passed with 87.46% in favour.
