The Raja Lumu Secondary School was established in 1982.
The school's land was first planned to be the school for Simpang Lima Tamil Primary School. But because of the location, the school was closed and became Putera Sekolah Tengku Ampuan Rahimah. Then, the school has moved to a new location and here became the hostel for Putera Sekolah Tengku Ampuan Rahimah dan Pulau Lumut. After it was renovated for a few years, the Raja Lumu Secondary School was estabalished.
On January 1, 1982, Mr. Mohammad Noribinin Taib have been appointed to be the school's first principal while Mrs. S. Sthipam as the supervisor of this school.
This school holds 2 schooling sessions. The morning session is for Form 3, Form 4 and Form 5 (ages 15 to 17) while the afternoon session is for Peralihan or Reform students, Form 1 and Form 2 students (ages 13 to 14). This is done to accommodate the large number of students attending the school.
