Kiai Haji Ibrahim bin Fadlil (1874–1932) was a prominent Islamic scholar and the second General Chairman of Muhammadiyah, succeeding K.H. Ahmad Dahlan. Born in Kauman, Yogyakarta, on May 7, 1874, he was the son of K.H. Fadlil Rachmaningrat, a Chief Justice of the Yogyakarta Sultanate during the reign of Sultan Hamengkubuwono VII. From a young age, K.H. Ibrahim pursued religious studies, including studying in Mecca for 7–8 years. Upon returning to Indonesia, he became a highly respected teacher, mastering Quranic recitation, the Arabic language, and possessing deep knowledge of Islamic jurisprudence (fiqh) and theology (tauhid).

In 1923, following the passing of K.H. Ahmad Dahlan, K.H. Ibrahim was appointed as the General Chairman of Muhammadiyah. Under his leadership, Muhammadiyah experienced significant growth, expanding its reach in Islamic propagation and education throughout Indonesia. He introduced the "Fonds Dachlan," an initiative providing scholarships for children from underprivileged families, and pioneered social activities such as mass circumcision events and public Islamic lectures.

In the field of education, K.H. Ibrahim was known for the sorogan and weton methods, combining in-depth study with collective learning. He also led a women's study group known as Pengajian Adzdzakirat, which greatly benefited the community.
