Haplogroup V is a relatively rare mtDNA haplogroup, occurring in around 4% of native Europeans. Its highest concentration is among the Saami people of northern Scandinavia (~59%). It has been found at a frequency of approximately 10% among the Maris of the Volga-Ural region, leading to the suggestion that this region might be the source of the V among the Saami. Haplogroup V has been observed at higher than average levels among Cantabrian people (15%) of northern Iberia, and among the adjacent Basque (10.4%).
