The Defence Medal 1940–1945 (Norwegian: Deltagermedaljen 9. april 1940 - 8. mai 1945/Deltakarmedaljen 9. april 1940 - 8. mai 1945) is the award rewarded to those military and civilian personnel who participated in the fight against the German invasion and occupation of Norway between 1940 and 1945. The Defence Medal 1940–1945 can be awarded both to Norwegian and foreign citizens. The medal may still be awarded due to the large number of participants in the defence of Norway during World War II and the difficulties tracking down all eligible recipients.
