Johan Peter Molin (born 17 March 1814 in Gothenburg; died 29 July 1873 in Ekudden near Vaxholm) was a Swedish sculptor.
Johan Peter Molins father was the baker Anders Molin, who lived in Gothenburg. In 1843, Molin travelled to Copenhagen to study with Herman Wilhelm Bissen. Later he lived in Paris and during eight years in Rome. From 1853 he taught at the Royal Swedish Academy of Fine Arts and two years later he was appointed professor in sculpting. In 1859 he completed the sculpture The Knife Wrestlers ("Bältespännarna"). Copies of this work exist in Gothenburg, in Stockholm and in other Swedish cities. His statue of Karl XII was unveiled in 1868 in Kungsträdgården in Stockholm, where also the Molin fountain is located. Some of his work was exhibited in London and Paris.
Molin won awards from the Order of Vasa, from the Order of the Polar Star, from the Order of St. Olav and from Pour le Mérite.
Some of his works are displayed at the Gothenburg Museum of Art, at Vänersborgs museum and at Kalmar konstmuseum, among other places
