Jelena Šubić (Serbian Cyrillic: Јелена Шубић; Jelena Nemanjić Šubić (Јелена Немањић Шубић)) was the daughter of Stefan Uroš III Dečanski of Serbia and the half-sister of Stefan Dušan.

After Mladen III Šubić's death, she ruled as his widow over Skradin and Klis.

Firstly, from the wife of Paul III, Catherine Dandolo from Venice, then Jelena Šubić, the mother of Ban Tvrtko I of Bosnia.

[2] The cities were subsequently given up, after the inhabitants showed unreadiness and some non-decisive fighting, with Đuraš ceding Skradin to Venice after the death of Dušan (December 20, 1355).

[2] Dušan had sought a flotilla from Venice for his planned campaign on Constantinople, and had ordered Đuraš to cede Skradin if it could not be defended from the Hungarians.
