Henrik Carstensen (30 October 1753 – 15 September 1835) was a Norwegian businessman, timber merchant and shipowner.

[1] Henrik Carstensen was born on the island of Risøya near the town of Risør in Nedenes county, Norway.

In 1788, he started trading in Risor in Søndeled, where he ran both a lumber and shipping business.

Over time, he bought forested acreage estates, operated sawmills and a distillery.

In 1833 he retired from the business, which he conferred upon his nephew, Carsten Henrik Carstensen (1796–1852), whom he had adopted in 1821.
