The British occupation of the Faroe Islands in World War II, also known as Operation Valentine, was implemented immediately following the German invasion of Denmark and Norway. It was a small component of the roles of Nordic countries in World War II.In April 1940, the United Kingdom occupied the strategically important Faroe Islands to forestall a German invasion. British troops left shortly after the end of the war.

The flag of the Faroe Islands is an offset cross, representing Christianity. It is similar in design to other Nordic flags – a tradition set by the Dannebrog of Denmark, of which the Faroe Islands are an autonomous territory.The flag is called Merkið, which means "the banner" or "the mark". It resembles the flags of neighbouring Norway and Iceland.
