Josephinum Academy of the Sacred Heart is a private, Roman Catholic, all-girls high school in Chicago, Illinois.

In September 1886, Mother Philomena Schmittdiel, superior of the North American Province of the Sisters of Christian Charity, buried a small statue of St. Joseph in an empty field across the street from St. Aloysius Church.

This was the symbol of her intention to buy the property on Oakley Boulevard and build a school for girls that she would call St. Joseph's Academy.

When the building opened to students in September 1890, a single Latin word, "Josephinum," which roughly translates as "the house of Joseph," was carved above the entrance portico.

The strong partnership between the Sisters of Christian Charity and the Society of the Sacred Heart that harkens back to the orders’ founders, Pauline von Mallinckrodt and Saint Madeleine Sophie Barat, lives on through the orders’ collaboration at Josephinum.
