Welcome to Saint Irenaeus!

We're so happy you're here. We'd like to thank you for checking out our church which has been part of the Cypress community since 1961 - a time when there were more cows than Catholics! We’re an active Catholic community striving daily to strengthen our relationship with God, embrace His message, and answer His call to serve and love one another.  If you've been looking for a way to nurture your faith, reconnect, get more involved, or simply for a place to pray, we welcome you with open arms!


Our church building is temporarily closed due to renovation.

Please join us for Mass at the flagpole or the hall.
