The Husby Estate (Norwegian: Husbygodset) is an estate in Helgeland, Norway. It is based in the village of Husby on the southwestern part of the island of Tomma in the municipality of Nesna.
Anders Christensen the younger (1751–1821), a shipper and a tradesman, and otherwise a great-great-grandson of the noblewoman Margrete Jonsdotter Benkestok, started in 1806 buying properties in Lurøy. He bought altogether twelve parts of the farms Grønningen, Kvitvær, Lunderøy, Måsvær, Sandvær, Sengstrag, Sør-Nesøy, and Trolløy. In 1819 he bought a part of Husby Farm, which until then had been a part of the Dønnes Estate.
After Christensen's death his widow Anna Catharine née Bernhoft continued buying properties. In 1825 she bought altogether nine parts of farms in the districts Meløy, Rødøy, and Lurøy. In 1833 she bought altogether twelve parts of farms in Lurøy. In 1834 she bought much land in the district Træna. Later followed the purchases of the trade seat Lurøysjøen, the trade seat Lauvøya, and Åkvik Farm.
Their son Frederik Christian Bernhoft Christensen (1800–1869) took over the Husby Estate. He was succeeded by his son Anders Christensen the younger (1840–1901). Anders Christensen married Johanne Marie Coldevin, the daughter of Isaach Coldevin, who was the owner of the considerably bigger Dønnes Estate. With her were 67 farm parts added to the Husby Estate. The estate thereby grew to consist of approximately 190 farm parts, making it a medium-sized estate in Northern Norway.
The couple's two daughters, Frederikke Christiane Christensen (1867–1887) and Jørgine Catharine Christensen (1872), did not reach adult age, wherefore the estate stood without heirs. Johanne Marie Christensen died in ca. 1895. In 1899 the widower Anders Christensen married Nathalie née Finchenhagen (1873–1955). Anders Christensen died in 1901, whereupon the widow inherited the estate. Nathalie had the Husby Chapel built to serve the local population in 1905.
