Barangay Sampaguita is in the Municipality of Mabini. It is just a few hundred meters away from the Poblacion or Town Proper. It was originally known as "Sitio Makokak" of P. Niogan (one of the oldest barangays in Mabini). She became one of the thirty-four (34) barangays in Mabini by the Revised Administration Code of the Barrio Chapter, Republic Act 3590 on January 1960. The former Municipal Mayor Rafael P. Amurao (the late father of the ex-mayor Ruben P. Amurao) name it after our natuional flower, SAMPAGUITA. Since that time, the Barangay Sampaguita came into existence.
