Infant Jesus Parish has been a strong and loving presence of God’s Kingdom in Port Jefferson and the surrounding areas since its founding over 100 years ago.  We are always mindful of the selfless giving of each succeeding generation of parishioners that has enabled Infant Jesus to continue its mission of new birth, renewed hope and lasting peace. From its founding by the Montfort Fathers, this parish has been a place where the grace of God has flourished because people have responded to all types of needs with a faith filled and generous spirit.  We invite to a deeper experience of participation as Church through volunteering.  If you would like to join one of our ministries, please contact the rectory at 631-473-0165 or email This email address is being protected from spambots.
