Siv is a Scandinavian feminine given name used primarily in Denmark, Sweden, and Norway. The name derives from the Old Norse Sif, which meant "bride" or "kinswoman". In Norse mythology, Sif was the wife of Thor, the god of thunder. The most famous mythological tale involving Sif is when the trickster Loki cut off her golden hair, prompting an enraged Thor to force Loki to commission a replacement from the dwarves, which ultimately led to the creation of other treasures for the gods. As a given name, Siv gained popularity in Scandinavia during the 20th century. In Norway and Sweden, it became especially common in the mid-century. Many notable modern bearers are Norwegian and Swedish politicians, athletes, or cultural figures.
