Rusovce (Hungarian: Oroszvár, Croatian: Rosvar German: Karlburg, Rossenburg, Kerchenburg) is a borough in southern Bratislava on the right bank of the Danube river, close to the Austrian border.

On 15 October 1947, together with Čunovo and Jarovce, Rusovce was annexed by Czechoslovakia according to the Paris Peace Treaty, in order to make possible to divert the Danube.

There are no more border checks at both crossings from 21 December 2007, with Hungary and Slovakia joining the Schengen Area.

Main sights include the ruins of the Roman military camp Gerulata, part of Limes Romanus, and Rusovce mansion built in the 19th century in the Neogothic style, located in the English park.

Dunajské luhy Protected Landscape Area comprises some parts of the borough and is located east of the municipality.
