The Girls' Greater Catholic League (abbreviated GGCL, formerly the Girls Greater Cincinnati League) is a high school sports league composed of 5 member schools in the Archdiocese of Cincinnati. Beginning with the 2013-14 school year, the league experienced a restructuring, the co-ed schools formerly in the GGCL, will now compete in the co-ed division (separate from the GGCL), the co-ed division schools will continue to play games against GGCL schools. Previously GGCL schools were split into two divisions The GGCL grey consisted of the co-ed schools, while the scarlet consisted of the all female schools. The mission of the league is to provide and promote a Christian atmosphere for the development of young ladies through interscholastic competition. Good sportsmanship and respect is of the utmost importance and school spirit will always be encouraged. The GGCL athletic activities are organized and supervised in harmony with policies of the member schools and the Ohio High School Athletic Association. The boys from the co-ed member schools compete in the GCL.
In 1966 the first league competition began among a group of girls' Catholic high schools in the area. Extramural games in basketball and volleyball were played among the schools in the next couple of years. Few records were kept and the league was loosely organized by some coaches and students.
This was not the first competition for these schools. Most had participated in play days and games for quite a few years. Prior to league competition, emphasis was placed on the social aspect of sport. The refreshments and social hour after the game were as important or more important than the game. Rivalries were friendly and the game scores incidental.
In the first years schools were represented at league meetings by interested teachers and often students were delegated to attend. At first, some educators resisted the formation of a structured league. As new people entered the schools and assumed responsibility for sports programs changes occurred in the league.
Structure was added to the league, rules and policies were made to meet the needs of the emerging girl athlete. Regular meetings were held and slowly the emphasis shifted from cookies and punch to skill development and highly contested games. League championships were held and many regular season games were well attended.
