La Festa Italiana Jersey City, Inc., was established in 2005 for Holy Rosary Church's annual Italian Festival. Since 1902, the parish has had a Street Festival in August coinciding with the Feast of Our Lady of the Assumption & St. Rocco.
This is the parish's largest fundraiser of the year. In an effort to raise additional funds through corporate sponsors, the 501 (C) (3) was formed as an Italian Cultural Preservation Organization. Each year, all proceeds from La Festa Italiana are donated to Holy Rosary Church for the continued preservation of the Church facilities.
