Lady of Neuville (French: Madame de Neuville-en-Artois) (died 1228) was the empress consort of Robert of Courtenay, Latin Emperor of Constantinople.
Though not actually closely related by blood, Eudokia was a stepdaughter of Marie de Courtenay who was third wife of Theodore I and sister to Robert.
She had been taken there by her paternal uncles Alexios and Isaac Laskaris who had left the Empire of Nicaea following the death of Theodore I.
According to William of Tyre Continuator, Robert and the Lady of Neuville were secretly married, despite her already being the fiancée of a Burgundian gentleman.
[7] Robert left Constantinople following the attack, seeking the assistance of Pope Gregory IX in re-establishing his authority.
On his return journey from Rome, Robert visited the court of Geoffrey I of Villehardouin of the Principality of Achaea.
