St John Brigade is the volunteer wing of the Priory for South Africa, of the wider international Order of St. John, dedicated to teaching first aid and home based care and the practice of these disciplines in communities across the country.

The St John Brigade uniform worn by members, is well known by many people and members are required to wear uniform when volunteering in the name of the Brigade, both for identification and to present a professional image.

It is protected by law[3] and may only be worn by registered members.

Unlike many volunteer groups, the St John uniform is relatively formal.

There are several orders of dress intended for different situations.
