Immaculata High School (also known as Immaculata, Lata, or IHS) is a private, coeducational, Roman Catholic high school in Somerville, in Somerset County, New Jersey, United States. Founded in 1962, Immaculata High School operates within the Roman Catholic Diocese of Metuchen. The school was also served by a group of Sisters, Servants of the Immaculate Heart of Mary, (from opening through the end of the 2018–19 school year) who lived in a convent attached to the main building of the school. Many of the Sisters taught different subjects in the school's curriculum. Immaculata High School has been accredited by Cognia since 2012.
