“As for my household, we will serve the Lord”
~Joshua 24:15


Welcome to St. Margaret Mary Catholic Church in Algonquin, Illinois. We welcome you to a strong and vibrant parish community that has been serving the Algonquin, Barrington Hills and Lake in the Hills communities for over 100 years. We just celebrated our 100th Anniversary in 2015, and we look forward to our next 100 years of being the active, friendly and growing faith community that has come to define us.

Being a parishioner means celebrating and making a commitment to Jesus Christ. If you are new to the Algonquin/Lake in the Hills community, or if you have not yet become a member of St. Margaret Mary, we encourage you to consider joining our community in worship and ministry.
