Tyrstead (Russian: Тирстед) is a Lovian hamlet in the state of Seven. Tyrsted is located on Philosopher's Island, north of Novosevensk. The village has seen many demographic shifts over the years. It was founded in 1892 by Scandinavian settlers, who originally named it Tyrsted after a parish in Denmark. By 1915, however, it had become heavily English-speaking, and in 1916 the village council decided on the new anglicised spelling of Tyrstead.
