The Battle of Kolding (Slaget ved Kolding) on January 9, 1644 was the opening engagement of the Torstenson War between the Swedish Empire and Denmark-Norway. The battle was primarily a cavalry engagement between Swedish and Danish cavalry near the Danish seaport of Kolding. The encounter was part of the wider Thirty Years' War, which saw heavy fighting in Central Europe. The Danish army made a defensive stand only to be overrun by the advancing Swedes. It was a decisive victory for the Swedish forces and by the end of January the Jutland peninsula was a Swedish possession.
