Live Mercy, Seek Justice

Merion Mercy Academy—located on the Main Line outside Philadelphia—is an all-girls independent Catholic college preparatory school for grades 9-12. Our personalized, holistic education is tailored to your student’s learning while furthering her emotional, creative and physical growth. We pride ourselves on our nurturing environment—our Merion Mercy sisterhood sits in high renown—and place our focus on educating the leaders of tomorrow. 

Merion Mercy is a sponsored ministry of the Institute of the Sisters of Mercy of the Americas and is a member of Mercy Education. Our foundress, Catherine McAuley, was a visionary who empowered those around her to do their part in making the world a better place. For 140 years, we’ve honored Catherine’s legacy through a faith-focused curriculum that stresses Mercy spirituality, global awareness, and social responsibility. We invite your student to step into her true potential, empowering her to live with an open heart, mind and spirit, and to always lead by example.

We are located in Merion Station, Pennsylvania ( just outside Philadelphia) and are proud to receive students from throughout the Delaware Valley and as far away as Ukraine, China and Brazil. 

 "Our name is mercy; our spirit is compassion." – Foundress Catherine McAuley
