The Convention of Moss (Mossekonvensjonen) was a ceasefire agreement signed on 14 August 1814 between the King of Sweden and the Norwegian government. It followed the Swedish-Norwegian War due to Norway's claim to sovereignty. It also became the de facto peace agreement and formed the basis for the personal union between Sweden and Norway that was established when the Norwegian Stortinget (Parliament) elected Charles XIII of Sweden as king of Norway on 4 November 1814. The Union lasted until Norway declared its dissolution in 1905.

The Swedish–Norwegian War, also known as the Campaign against Norway, War with Sweden 1814, or the Norwegian War of Independence, was a war fought between Sweden and Norway in the summer of 1814. According to the Treaty of Kiel, Norway would enter a union with Sweden under Charles XIII of Sweden. The war resulted in Norway being forced into the United Kingdoms of Sweden and Norway, but with its own constitution and parliament. The war marked the last time Sweden participated in an armed conflict with another nation, and its conclusion signalled the beginning of the country's long period of military neutrality.
