Denmark/Sweden is a less popular slash pairing involving the characters of Denmark and Sweden. The pairing surged into popularity alongside Norway/Iceland back when Denmark and Norway's designs first came out and the western Hetalia fandom was growing rapidly. The pairing seems to have dropped in popularity over time while Denmark/Norway has grown and Norway/Iceland has remained popular. The Denmark/Sweden pairing is often referred to as "DenSu", "DenSwe", "SweDen", "SuDen", or "SweDenmark".
