The girl who was with a group of about a dozen tourists was killed after falling 40 meters ( 131 ft) from a viaduct over the Cedeja riverbed on Monday evening, the second bungee death in Spain within a month.
Her body landed in the dry riverbed and was retrieved by the emergency services on Monday night.
It was reported that the teenager was staying with a group at a campsite in nearby Oyambre and that the jump was organized by a local adventure company.
"Apparently, she was not fully secured when she jumped," Esther Merino, a councillor from Cabezón de la Sal, a town 50 kms (31 miles) west of Santander, told AFP about the accident Monday evening.
Local Police said the circumstances of the death were as yet unclear but suggested that bungee jumping at that point may not have been authorized.
"We had no idea that bungee jumping was carried out there where it is extremely risky," Joaquin Gonzalez, the Local Police chief told regional newspaper El Diario Montañes.

The Foreign Ministry in the Netherlands has confirmed the death of a Dutch national in Cantabria.
In July, Londoner Kleyo De Abreu, 23, was killed during a bungee jump in Lanjaron, Granada.
Two people face charges of manslaughter over her death, the owner of an adventure company that organized the jump at the Tablate bridge and the jump supervisor.
