Sigurd Simensen (19 February 1888 – 27 April 1969) was a Norwegian newspaper editor and politician for the Labour and Communist parties.
In 1918 he was elected to the Labour Party central board, and was hired as travelling secretary for Northern Norway.
He also chaired the national association of worker's councils which sprang up in the same year, post-Russian Revolution.
"Hammerfest was the only city where something resemblant to a revolutionary situation ensued", wrote historian Per Maurseth.
During the Second World War's German occupation of Norway, Simensen was engaged with forced labour.
