The Vipera seoanei or Baskian viper, Iberian cross adder, Portuguese viper is a venomous viper species found in extreme southwestern France and the northern regions of Spain and Portugal. Two subspecies are currently recognized, including the nominate race described here.
Adults may grow to a length of 75 cm, but usually less.
This species is classified as Least Concern (LC) according to the IUCN Red List of Threatened Species. It was given this status due to its relatively wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
