Sacred Heart-Griffin High School

Sacred Heart-Griffin High School, often abbreviated SHG, is a Catholic high school located in Springfield, Illinois, United States. It is the city's largest private school and is located in the Diocese of Springfield in Illinois.

The school opened in the fall of 1988 after Sacred Heart Academy, an all-girls Catholic high school merged with Griffin High School, an all-boys Catholic high school located across the street. Even prior to the merger, certain classes at both schools were taught on a co-educational basis.

The part of campus which formerly housed Griffin High School is now known as the West Campus. The part of campus which was home to Sacred Heart Academy is known as the East Campus. Both facilities are used by SHG, with most of the school's athletic facilities being located on the West Campus and the majority of the academic facilities being located on the East Campus. On the school's East Campus is a motherhouse for a Dominican order of religious sisters.

All of the sports teams are known as the "Cyclones". In the fall the school offers football, cross country, boys' soccer, boys' and girls' golf, girls' swimming, volleyball, and girls' tennis. In the winter SHG has boys and girls' basketball, cheerleading, hockey, poms, boys swimming, and wrestling. In the spring, baseball, softball, girls soccer, boys and girls track, and boys tennis are played.
