St. Patrick Roman Catholic Church serves the spiritual, sacramental, liturgical and other needs of the Catholic community in and around the Smithtown area of Suffolk County on the north shore of Long Island, located midway between New York City and the eastern tip of Long Island.

The parish first took root in the Hauppauge/Smithtown area in the mid-1830’s. From the first few founding Catholic families, the parish began to grow rapidly. Mass was first held, very much like the earliest Christians, in local farmhouses.

Originally a ‘mission church,” St. Patrick’s became a full parish in 1952, and moved to our current location in 1966. The new location provided ample space for a church, rectory, school, convent, athletic fields and ample parking to accommodate the needs of the ever growing number of new suburban families moving to Smithtown. Our church and parish have a very rich history which includes its very small beginnings, harassment by the Ku Klux Klan, devastating fires, and explosive growth. To read a more complete history, please see the parish history write up available on this page.

Today, the parish supports a vibrant community and offers many services to our parishioners and neighbors. Msgr. Ellsworth Walden is our current pastor. He and the associate priests provide the parish with excellent pastoral care along with all the staff at the rectory, the nerve hub of the parish. Other priests living at the rectory, serve as chaplains at St. Catherine’s Hospital in Smithtown, and area nursing homes.
