The Greater South Shore Conference is an eight-member Indiana High School Athletic Association athletic conference spanning Lake and Porter counties in Northwest Indiana. Two other members, Boone Grove and Gary West Side, participate only in football, with Boone Grove otherwise participating in the Porter County Conference and Gary West Side otherwise participating in the Great Lakes Athletic Conference.
Hanover Central High School joined the conference in 2013, Griffith High School joined the conference in 2017, and Illiana Christian High School joined the conference in 2021. Marquette Catholic High School and North Newton High School left the conference concurrent with Griffith joining, with Marquette becoming an independent and North Newton joining the Midwest Conference. The conference has two divisions for football, with the North Division including Boone Grove, Hammond Bishop Noll, Lake Station Edison and Whiting, and the South Division including Calumet, Gary West Side, Griffith, River Forest and Wheeler. Illiana Christian does not have a football team.
Due to continued rapid growth, Hanover Central left the conference in 2023 to join the Northwest Crossroads Conference. Gary West Side joined as a football-only member upon Hanover Central's departure. Illiana Christian, also growing quickly, has announced its intention to leave the conference in 2026 to join the Northwest Crossroads Conference.
In 2026–2027, Boone Grove Girls Tennis will join the Greater South Shore Conference.
