Poul Steenstrup (10 December 1772 – 9 October 1864) was a Norwegian industrialist and politician.

[1][2] Poul Steenstrup was born the son of a Danish landowner at Egtved, in Vejle, Denmark.

From 1801 he undertook a three-year scholarship trip to German and Austrian ironworks and factories, principally in Freiberg and Vienna.

In 1813 he managed to win the backing of Prince Regent Christian Frederik (later Christian VIII of Denmark) to establish Norway's first factory, the Kongsberg Arms Factory (Kongsberg Våpenfabrikk) which opened in 1814.

[4][5][6] Poul Steenstrup represented Kongsberg at the Norwegian Constituent Assembly in 1814.
