Hector Livius van Altena (1741 – 11 April 1806) was a Dutch lawyer and politician who played a significant role in Frisian politics during the late 18th century.

Despite his considerable wealth, he arrived there destitute and was granted financial assistance by the French government amounting to 24 livres per week.

[3] On 11 September 1801, Van Altena was granted financial compensation of 39,947.17 guilders for the losses he had suffered due to his exile in 1787 and the subsequent years.

[3] Following the Batavian Revolution of 1795, Van Altena was appointed as a member of the Representative Body of Friesland.

[2] On 23 June 1795, in elections for Friesland's permanent administration, Van Altena was chosen as a representative for Dantumadeel.

He aligned himself with the radicals and continued to follow Van Beyma until the latter adopted a more federalist stance, particularly in financial matters.

On 4 May, a proposal for new elections was introduced, ensuring that all sitting members would retain their seats, following the precedent set in France in October 1795.
