Luther College is a co-educational independent secondary school of the Lutheran Church of Australia located in the outer-eastern suburb of Croydon Hills in Melbourne, Victoria, Australia. It maintains a close relationship with the Outer Eastern Lutheran Church parish of the Lutheran Church of Australia, which congregates in the school's chapel facilities. It provides education for years 7–12.

Opened in 1964, Luther College is a school of the Lutheran Church of Australia, named for the father of the Lutheran Church, Dr. Martin Luther, a 16th-century German theologian.

Formally a boarding school, Luther College accepted international and regional boarders in addition to local day students. However, after a decline in international enrolment and worries about the growth of the student body in relation to the school's facilities, the boarding program ended at the end of 2002, with the associated facilities subsequently adapted into classrooms or demolished.

As a school of the Lutheran Church of Australia, Luther College students participate in mandatory religious education classes in all years.

All students from all year levels attend a chapel service in the school's chapel three days out of the week, with one year level assembly and one day being an extended homegroup.

The school's campus contains a special Ministry Centre which contains the offices of the school's two chaplains as well as the school counsellor.

Both Luther College and The Good Shepherd Lutheran Primary School are private schools, as well as schools of the Lutheran Church of Australia. Both their campuses are located in Croydon Hills, separated by two sporting ovals.

The schools share many of their facilities, including the sporting ovals, as well as the Luther College chapel which is used by the primary school for special occasions. The schools have very similar uniforms, and until 2004 their physical education uniforms were almost identical.
