Niels Christian Frederiksen (Friderichsen) (23 March 1840 - 4 November 1905) was a Danish national economist, businessman and politician.

Frederiksen was born on 23 March 1840 at Fuglsang Manor on Lolland, the son of Hohannes D. Friderichsen (1791-1861) and Maria Hansen (1811-1901).

He won the university's gold medal in 1859 for a thesis on the influence of grain prices on wage levels.

His competition piece, Er den frie Konkurrence under alle Omstændigheder i Almenvellets Interesse?

He ran with a programme of rather radical political reforms but most likely won due to the local popularity of his father.

With great enthusiasm, he cultivated the land, purchased livestock, planted forest and established workshops and saw mills.

In Copenhagen, he obtained citizenship as merchant (grocererborgerskab) to be able to sell his products and established a successful trading house.

Industribanken raised concerns and discontinued all loans, resulting in the bankruptcy both of Frederiksen and his brothers.

The business venture initially prospered, growing to a considerable size, but Frederiksen once again adopted a too risky strategy and he also failed to keep track of the many transactions.
