Christen Knudsen (25 January 1813 - 7 April 1888) was a Norwegian ship-owner.
Their sons Jørgen Christian Knudsen and Gunnar Knudsen both became wealthy ship-owners and influential politicians: Jørgen Christian as mayor and parliament member, Gunnar as Prime Minister of Norway.
Their only daughter Serine married Johan Jeremiassen[1] and had a political career of her own, starting even before women's suffrage was introduced.
[1] Together with P. M. Petersen and son-in-law Johan Jeremiassen he was described as one of "the three large ship-owners of the city".
[1] A ship belonging to his son Gunnar was named Christen Knudsen, but this was sunk by the Kaiserliche Marine in 1916.
