Şimşekler Grubu is one of the best-known organised supporter groups associated with Adana Demirspor and the club’s blue-and-navy supporter culture.
The group has remained highly active during the club’s recent financial and sporting crisis. In 2025, Şimşekler Grubu launched a support campaign under the ‘Yaşasın Demirspor’ slogan, and in February 2026 the club announced that management had passed to a new structure formed under the group’s leadership.
Its mobilisation continued in 2026 through public appeals, fundraising activity and the organisation of a large ‘Yaşasın Demirspor’ march in Adana, reflecting the group’s central role in efforts to protect the club’s future.
