The Sjölejonet class was a series of nine coastal patrol submarines operated by the Swedish Navy during World War II and early Cold War. The boats were developed as part of a Navy modernization program intended to counteract Germany during the late 1930s. The boats were the first indigenous Swedish design, and incorporated unique weapons. During World War II, the boats conducted patrols along the coast to maintain Swedish neutrality. By the start of the Cold War, the vessels were retrofitted before being withdrawn from service by the early 1960s and being replaced by the Sjöormen class.
