La Gloriosa Butteler is an organised supporter group associated with San Lorenzo and the club’s blue-and-red terrace culture.
The group has a recognised place within San Lorenzo’s organised supporter scene and is active through banners, public statements and matchday support.
La Gloriosa Butteler remained clearly active in 2025. In May, the group publicly displayed and shared a banner directed at club president Marcelo Moretti during a period of institutional controversy at San Lorenzo.
