Vinoviloth are one of the tribes in Scandinavia mentioned by Jordanes in De origine actibusque Getarum in the 6th century CE. It has been suggested that they would have been the same as the Winnili. Sometimes Vingulmark is also mentioned. Jordanes writes:
And there are beyond these the Eastern Geats (Ostrogothae), Romerike (Raumarici), Rånrike (Aeragnaricii), and the most gentle Sami people (Finni), milder than all the inhabitants of Scandinavia (Scandza). Like them are the Vinoviloth also.
Besides Getarum, the Vinoviloth are not mentioned anywhere else.
