Victoria, Crown Princess of Sweden, Duchess of Västergötland is the heir apparent to the Swedish throne, as the eldest child of King Carl XVI Gustaf. If she ascends to the throne as expected, she would be Sweden's fourth queen regnant and the first since 1720. Her inheritance is secured by Sweden's 1979 Act of Succession, the first law in Western Europe to adopt royal absolute primogeniture.

An heir apparent or simply heir is a person who is first in an order of succession and cannot be displaced from inheriting by the birth of another person. A person who is first in the current order of succession but could be displaced by the birth of a more eligible heir is known as heir presumptive.
