HDMS Dannebroge was a Dano-Norwegian ship-of-the-line that exploded and sank on 4 October 1710, during the Great Northern War.

Dannebroge was built in 1692 and she was the largest ship-of-the-line in the Dano-Norwegian navy at that time with her 84 cannons placed on two decks and a crew of 600 men.

The mission was to escort 6,000 Russian troops to the Danish capital of Copenhagen, so they could support Denmark–Norway during the Great Northern War against the Swedes.

According to the commander in chief of the Dano-Norwegian navy, Ulrik Christian Gyldenløve, the fire on Dannebroge was probably ignited by her own cannons.
