"Sekolah Menengah Kebangsaan Datin Onn Jaafar (SMKDOJ)" is better known as DOJ or "Pesta" by most of the residents in Batu Pahat, and was established in early 1977. The first schooling session started on 1 January 1978.

It is located in Batu Pahat on a land area of 10 acres (4 hectares). The school began construction in early 1977 and was completed in the same year.

The school was previously named as "Sekolah Rendah Bandar Penggaram". The name was later changed to "Sekolah Menengah Datin Halimah" in commemoration of the wife of former Malaysian Prime Minister, Dato Onn Jaafar. However, the PM's wife disagreed with this and it was later changed to "Sekolah Menengah Kebangsaan Datin Onn Jaafar", a name it still retains.

SMK Datin Onn Jaafar was formally opened on 1 September 1977 by former Malaysian Prime Minister, Tun Dr. Mahathir bin Mohammad, who at the time was Minister of Education.
