The Duchy of Styria (German: Herzogtum Steiermark; Slovene: Vojvodina Štajerska; Hungarian: Stájer Hercegség) was a duchy located in modern-day southern Austria and northern Slovenia. It was a part of the Holy Roman Empire until its dissolution in 1806 and a Cisleithanian crown land of Austria–Hungary until its dissolution in 1918.

It was created by Emperor Frederick Barbarossa in 1180 when he raised the March of Styria to a duchy of equal rank with neighbouring Carinthia and Bavaria, after the fall of the Bavarian duke Henry the Lion earlier that year. Margrave Ottokar IV thereby became the first Duke of Styria and also the last of the ancient Otakar dynasty. As Ottokar had no issue, he in 1186 signed the Georgenberg Pact with the mighty House of Babenberg, rulers of Austria since 976, after which both duchies should in perpetuity be ruled in personal union. Upon his death in 1192, Styria as stipulated fell to the Babenberg duke Leopold V of Austria.

The Austrian Babenbergs became extinct in 1246, when Duke Frederick II the Quarrelsome was killed in battle against King Béla IV of Hungary. Styria, actually a ceased Imperial fief, due to the lack of a central authority after the deposition of Emperor Frederick II of Hohenstaufen evolved into a matter of dispute among the neighbouring estates. It passed quickly through the hands of Hungary in 1254, until the Bohemian king Ottokar II Přemysl conquered it, being victorious at the 1260 Battle of Kressenbrunn. As King Ottokar II had married the last duke's sister Margaret of Babenberg he laid claim to both Austria and Styria, which however met with strong opposition by the elected German king Rudolph of Habsburg, who now recalled the duchies as reverted fiefs. Rudolph finally defeated Ottokar at the 1278 Battle on the Marchfeld, seized Austria and Styria and granted them to his sons Albert I and Rudolf II.
