The Grunwald Swords (Polish: miecze grunwaldzkie) were a gift presented by Ulrich von Jungingen, the Grand Master of the Order of Teutonic Knights, to King Władysław II Jagiełło of Poland and Grand Duke Vytautas the Great of Lithuania on 15 July 1410, just before the Battle of Grunwald (Tannenberg). The gift, a pair of simple bare swords, was a formal invitation to the battle. After the Polish-Lithuanian victory, both swords were taken as a war trophy by King Władysław II to Kraków, Poland's capital at the time, and placed in the treasury of the Royal Wawel Castle.

With time, the two swords became treated as royal insignia, symbolising the monarch's reign over two nations, the Kingdom of Poland and the Grand Duchy of Lithuania. They were probably used in coronations of most Polish kings from the 16th to the 18th centuries. In private hands after the partitions of the Polish-Lithuanian Commonwealth at the end of the 18th century, they were lost without a trace in 1853. They have remained, however, a symbol of victory and Poland's and Lithuania's past, and an important part of national identity of the two nations.

The battle of Grunwald was part of the Great War fought during 1409–1411 between a Polish-Lithuanian coalition led by King Władysław II and Grand Duke Vytautas (Alexander) on one side and the Teutonic Order aided by West European knights and led by Grand Master Ulrich von Jungingen on the other side. It was a decisive battle of the war and one of the largest in medieval Europe.
