Lac de la Haute-Sûre (French pronunciation: [lak la ot syʁ]; Luxembourgish: Stauséigemeng; German: Stauseegemeinde, pronounced [ˈʃtaʊzeːɡəˌmaɪndə]) is a commune in the canton of Wiltz, in north-western Luxembourg. The commune is named after the Upper Sûre Lake, a reservoir on the upper Sauer river. Its administrative centre is Bavigne.

Lac de la Haute-Sûre was formed on 1 January 1979 from the former communes of Harlange and Mecher, both in Wiltz canton. The law creating Lac de la Haute-Sûre was passed on 23 December 1978.

In mid-2025, formal talks were launched between Lac de la Haute-Sûre and neighbouring Boulaide for a future merger of the two communes, with a referendum on the matter planned to be held before the 2029 communal elections. If successful, the merger would created the third largest commune in Luxembourg, after Wincrange and Clervaux.
