The Oak Yellow Underwing (Catocala nymphagoga) is a species of moth in the Noctuidae family.

This species is an extremly rare vagrant to Britain, with only three records. The first was in Wales in July 1982, the second three days later in the New Forest, Hampshire. The third was in Buckingham Palace in September 2002. This species is smaller than it's similar species such as the Red Underwing, and, as it's name suggests, it has a yellow underwing. Found in southern Europe, this species is becoming a more regular migrant to central Europe, so it could be soon when the next one occurs in Britain.
