Marina Smilets of Bulgaria

Marina Smilets (before 1292 – 7 April 1355) was a Bulgarian princess, the eldest daughter of Tsar Smilets and his Byzantine wife. She married Aldimir, the Terterid despot of Kran, and bore him a son, Ivan Dragushin. After Aldimir was possibly killed around 1305, she fled with the boy to Serbia, where her sister Teodora was the first wife of King Stefan Dečanski.

As the maternal aunt of Stefan Dušan she remained close to the Serbian court, and her donor portrait survives at the Pološko Monastery near Kavadarci.
