Countess Emilia Broel-Plater (Lithuanian: Emilija Pliaterytė; 13 November 1806 – 23 December 1831) was a Polish–Lithuanian noblewoman and revolutionary from the lands of the partitioned Polish–Lithuanian Commonwealth. Raised in a patriotic tradition in Līksna near Daugavpils, she fought in the November Uprising of 1830–1831 against the Russian Empire. She raised a small unit, participated in several engagements in present-day Lithuania, and received the rank of captain in the Polish insurgent forces. When the main forces under the General Dezydery Chłapowski decided to cease fighting and cross into Prussia, Plater vowed to continue the fight and wanted to cross into Poland where the uprising was still ongoing. However, she fell ill and died.
