The earliest reference to Duga Resa is from the year 1380. There are several theories on how the then-village acquired its name: one is that "resa" is a reference to the town people's folk costumes; another is that it is named from a native plant that grows in the area, both on the land and in the water.
The village soon grew into a town during the industrialization of the area in the late 19th and early 20th century. In the 2001 census, there were 12,114 inhabitants in the municipality, 96% of which were Croats.
