The Royal Institution of Chartered Surveyors (RICS) is a professional body representing and regulating property professionals and surveyors of all types. The institution originated in and is based in the United Kingdom but as at 2005 has a worldwide membership of over 120,000 in more than 100 countries.

The institution was founded in London in 1868 as the "Institution of Surveyors" and has occupied headquarters on the corner of Great George Street and Parliament Square since that date. The institution received its Royal Charter in 1881 and became the "Institution of Chartered Surveyors" in 1930. In 1946 the institution became a royal institution entitled to add "Royal" to its name and, thereby, achieved its present name.

The majority of members are based in Britain, however there is a strong international membership in many Commonwealth countries such as Canada, Hong Kong and Australia and membership is growing rapidly in the United States and in countries across Europe, Asia and Africa. The RICS has close links with many national surveying institutions and is a member association of the International Federation of Surveyors (FIG).

Outside of the United Kingdom (and particularly in non-Commonwealth countries), the institution generally avoids the use of the full name including "Royal" and styles itself as "RICS".
