Klinckowströmfjorden is the eastern branch of Raudfjorden at Spitsbergen, Svalbard, on the divide between Albert I Land and Haakon VII Land. It is named after Swedish zoologist Axel Klinckowström. The glacier Raudfjordbreen debouches into the fjord.[1] The peninsula Buchananhalvøya separates Klinckowströmfjorden from the western fjord branch Ayerfjorden.[2] The mountain Ben Nevis is located southeast of the fjord.
