Tureholm is a small and uninhabited artificial river island in Bäveån, which runs through the city of Uddevalla in Bohuslän, Sweden. It was created in the late 1800s or early 1900s by the local politician and publicist Ture Malmgren (1851–1922), close to his residence Villa Elfkullen. According to his newspaper Bohusläningen, the process of land reclamation took place because Malmgren enjoyed water, and wanted to be closer to the river. According to another author, it partially functioned as a wave breaker, preventing the ice of the late winters from pulling the nearby bridge with it. A small bridge is said to have formerly led from the mainland to its now overgrown embankments. The islet was named in reference to Malmgren by his friends. Other places named for him include the ruined Tureborg Castle and the nature reserve Ture Valleys.
