Augustenborg has a population of 3,160 (1 January 2023).^[1] It was the main town of Augustenborg Municipality until its merger into Sønderborg Municipality in 2007.

The town grew up around Augustenborg Palace which was established by Ernest Günther, a member of the ducal house of Schleswig-Holstein (its branch of Sønderborg) and a cadet of the royal house of Denmark, in the years after 1651. The palace, and the town consequently, received the name in honor of Ernest's wife Auguste, herself also from a branch of dukes of Schleswig-Holstein.

The palace became the chief seat of their line which used the name Augustenborg as its branch name. Later, a Danish king made the head of that line specifically Duke of Augustenborg. They grew in relative prominence in late 18th century, and in the 19th century Schleswig-Holstein Question, being the symbols of pro-German nationalistic movement in Schleswig-Holstein. The area was annexed by Prussia in 1864 from Denmark, but was returned in 1920 following a plebiscite.

The Augustenborg male line died out in 1931, upon the death of Albert, Duke of Schleswig-Holstein, a grandson of Queen Victoria. Their female-line descendant today holds the throne of Sweden.
