Jørgen Johannes Havig (July 31, 1808 – January 19, 1883) was a Norwegian bailiff (lensmann), farm owner, and politician.
He is regarded as a driving force behind the founding of Namsos,[1][2] which was established as a "small seaport" (Norwegian: ladested or lossested) in 1845.
[1] He never received formal schooling, but was taught by his father (who was trained as a teacher), the attorney Søren Reiersen Thornæs, and the dean Peter Christian Boye, and he is said to have been particularly talented in mathematics, astronomy, and French.
In order to simplify timber exports, he worked to construct a small seaport with a customs office in Namdalen.
In 1845, Namsos was founded at the mouth of the Namsen River, and Havig even contributed to surveying and distributing the plots of land.
