Princess Teofila Ludwika Zasławska ( – November 15, 1709) was a member of the Polish nobility (), known as the perhaps most significant heiress and landowner of her contemporary Poland.
She was the daughter of Katarzyna Sobieska, who was the sister of Jan III Sobieski, the king of The Kingdom of Poland and the Grand Duchy of Lithuania. Her father was Władysław Dominik Zasławski, a Polish nobleman of Ruthenian stock of the house of Ostrogski, one of the richest magnates in Poland.
Teofila Ludwika Zasławska was an heiress of the Ostrogski family, one of the great Ruthenian princely families of the Grand Duchy of Lithuania. She was the fifth ordinate of the Ostrogski Ordination (one of the largest landed estates in the Polish–Lithuanian Commonwealth). Her father was the third, and one of her sons would become the sixth ordinate of it.
