The Lawrence Campbell Oratory Competition is an annual competition in impromptu public speaking between representatives of each of the Great Public Schools (GPS) and Combined Associated Schools (CAS) in New South Wales, Australia. It was established in 1935, in honour of Lawrence Campbell, a famous teacher of elocution in various schools in Sydney, New South Wales, in the early twentieth century. Between 2006-2013, in all but one year (2009), the competition was won by a student in year 11. At the 2015 World University Debating Championships in Malaysia, three of the eight speakers in the Grand Final (representing Sydney, Oxford, and Harvard) were former Lawrence Campbell winners - a testament to the quality of the Lawrence Campbell competition.
