No, it is not illegal to marry your first cousin in Alaska. The state permits first-cousin marriages under its statutes, which only prohibit unions between closer relatives like siblings, parents and children, or aunts/uncles with nieces/nephews.
Legal Basis
Alaska Statute AS 25.05.021 explicitly allows first cousins to marry by excluding them from the list of prohibited relationships. Marriage license applications require disclosing blood relations, but first cousins face no barriers.
Broader Context
Alaska aligns with about half of U.S. states permitting first-cousin marriage, with no criminal penalties or voiding of such unions. First cousins once removed and half-cousins are also allowed.
