Fontbonne Academy is a private Roman Catholic college preparatory high school for girls, located in Milton, Massachusetts, United States.

The school has a seven-acre campus with the original building that has been updated over the years to include science, technology and language labs.

[citation needed] Founded in 1954, the academy takes its name from Mother St. John Fontbonne, who re-established the congregation in France after its suppression during the French Revolution.

In Boston, the congregation taught in archdiocesan parochial schools, and also founded and conducted its own ministries, of which Fontbonne is one.

As a sponsored ministry, Fontbonne Academy furthers the Sisters' charism — a direct outgrowth of the order's experience in revolutionary France — of reconciliation, unity and non-violence in the school's academic programs, spirituality, and co-curricular activities.
