St. Olav's Medal with Oak Branch is a Norwegian military award, which was instituted by King Haakon VII of Norway on 6 February 1942.

Of all orders and decorations in Norway, both military and civil it is ranked as number six, then after King Haakon VII's Cross of Liberty but at the same time before Medal for Heroic Deeds.

The Medal is made of silver, and the tie contains the same colours found in the Norwegian flag.

The Medal also bears the inscription "HAAKON VII * KING OF NORWAY * EVERYTHING FOR NORWAY" (in Norwegian "Haakon VII * Norges Konge * Alt for Norge").

It has been awarded to 779 Norwegians, including one woman; a few non-Norwegian citizens have also received the medal.
