Welcome to Old St. Mary’s!

Welcome to all!

Thank you for visiting our website and, perhaps, visiting our church!

For many people visiting for the first time, their immediate question is “When Is Mass?” So, here you go:

  • Sundays: 8 a.m., 11 a.m. and 6 p.m.
  • Saturdays: Noon (Daily Mass) and 5 p.m. (Anticipated Mass for Sunday)
  • Monday to Friday: 8:30 a.m.


If you’ll be visiting us, you may want to check out our Holy Days schedule or directions to our parish and parking information.

We hope that you do visit us for Mass or a special event sometime soon. Whether you live in Chicago or surrounds, or are visiting our city, please know that everyone is welcome at St. Mary’s ― regardless of where you are in your faith journey or your life journey.

(You do not need to be Catholic to join us for Mass and special events! Feel free to just come and check us out!)

Did you know that, while our church building is fairly new, that we are the oldest Catholic parish in Chicago? We invite you to read all about our parish’s long and rich history.

For our new visitors, another important to thing to know is that our parish is served by the Paulist Fathers, a missionary society of Catholic priests working in evangelization, reconciliation and ecumenical and interfaith affairs. (The Paulist Fathers have been called “America’s friendliest priests.”)

If you have any other questions for us, don’t hesitate to give us a call at (312) 922-3444. We would love to get to know you and welcome you to our parish!
