Euphemia de Ross

Euphemia de Ross (c. 1329–c. 1389) was a daughter of Hugh, Earl of Ross, and sister of Earl William. She first married John Randolph, 3rd Earl of Moray, who was killed at Neville's Cross in 1346, leaving her large widow's estates including Badenoch.

Before May 1355 she married Robert Stewart, nephew and heir of David II. When he became Robert II in 1371 she was queen, but her coronation at Scone was delayed to 1372–1373, possibly in part because of disputes over her sons' succession rights. Her son David gained Strathearn and Caithness. She died around 1389 and was buried at Dunfermline Abbey.
