Davislaguna is a lagoon in Sørkapp Land at Spitsbergen, Svalbard. It has a length of about 900 meters, and is located at the foot of the mountains of Hedgehogfjellet and Tvillingtoppen. The name Davislaguna is derived from the name Lady Davis Harbour, given to the lagoon by members of an expedition from 1919. In 1937 the alternative name Dorrieshamna was also suggested.
