The style of the Swedish sovereign is the formal mode of address used by the reigning monarch of Sweden.
Its precise form has changed over the years, by either geopolitical change or replacement of ruling house.
This list only include monarchs subsequent to the reign of Gustav I in the 16th century, specifically since 1523 when he was elected king.
Due to him, the House of Vasa came to be the first monarchical dynasty to rule a unified Swedish kingdom.
Prior to his process of radical change, the Kingdom of Sweden was part of the Kalmar Union and was ruled by many different petty kings before that.
