Kjeld Stub Irgens (23 May 1879 – 26 August 1963) was a Norwegian politician during the German occupation of Norway.

He was born in 1879 to vicar Jens Stub Irgens and his wife Sophie Cathinka, née Altschwager. He had several brothers and sisters.^[1] He was a distant relative of eighteenth-century bishop Ole Irgens and politicians Ole and Johannes Irgens.^[2]

A sea captain by profession, Irgens had received his education in the Royal Norwegian Navy, which he left with the rank of First Lieutenant (Norwegian: Premierløytnant) in 1903.^[2] From 1913 onwards Irgens worked for the Norwegian America Line (NAL) shipping company, in 1918 assuming command of the NAL's 12,977 GRT passenger ship SS Stavangerfjord.^[3] In 1921 Irgens purchased the island of Ravnøy in Vestfold on behalf of the crew of Stavangerfjord,^[4] as a holiday resort at which to spend time with their families after spending long periods of time at sea. The 270-decare property, located between the island of Nøtterøy and Stokke on the mainland, was bought at a price of 10,000 Norwegian kroner and later transferred to the Norwegian America Line. The shipping company remained in ownership of the island until 1983 when it was sold on to the Holiday Resort Ravnøy Foundation (Norwegian: Stiftelsen Feriestedet Ravnøy).^[5]

As part of the legal purge in Norway after the war, in 1945, Irgens was sentenced to seven years of forced labour. The case was taken to the Supreme Court in 1946, where the sentence was increased to fifteen years.^[7] He died in 1963.
