Immaculate Conception Parish - designated for Polish immigrants in Southington, Connecticut, United States. Founded on September 19, 1915. It is one of the Polish-American Roman Catholic parishes in New England in the Archdiocese of Hartford.
In 1904 the Polish immigrants organized the Guardian Angel Society in an effort to found a Polish parish. In 1906, a committee of the society asked Bishop Michael Tierney for a Polish priest. None was then available. By 1910 Bishop John Joseph Nilan sent Fr. John Sullivan to serve the immigrants within St. Thomas Parish. A new Polish Catholic parish was officially approved in September 1915 by Bishop John Joseph Nilan. Property was secured as a future church site, along with a house to serve as a rectory. On September 19, 1915, Fr. Woroniecki celebrated the first parish Mass at a hall belonging to the Polish Falcons. On July 9, 1916, Bishop John Joseph Nilan dedicated the basement church of Immaculate Conception Parish. The completed church was finally dedicated on October 28, 1923.
