St John is a major international charity which provides first aid, health care and support services in over 30 countries around the world. Together they make up the Order of St John, which is accredited to the United Nations.

The Order's charitable work is carried out by the St John Eye Hospital in Jerusalem and national St John organisations worldwide – with volunteers and staff of over 245,000.

The Order of St John itself is an Order of Chivalry of the British Crown. Her Majesty The Queen, the Head of the Order, honours individuals who have made outstanding contributions to the work of St John, by awarding membership, at different grades, in the Order.

The Order is also a Christian Order. It was founded on Christian principles and is motivated by Christian ideals. It, however, warmly welcomes people of any faith or of no faith, who are motivated to share in our mission.
