Eudokia Laskarina Angelina (Greek: Ευδοκία Λασκαρίνα Αγγελίνα, born between 1210 and 1212, died after 1247) was a Byzantine princess.

She was a younger daughter of Emperor Theodore I Laskaris of Nicaea and Anna Komnene Angelina.

[1] She was engaged to Robert I, Latin Emperor in 1221, but the marriage was blocked by the Patriarch of Constantinople.

[2] In 1247, Anseau assigned to her custody of the city of Tzurulon in the hope that it would not be attacked by John III Doukas Vatatzes, who was married to Eudokia's sister Irene Laskarina.

[3] Her name was Eudokia, but in one western source, related to her Austrian marriage, she is mentioned as Sophia.
