The Royal Institution of Chartered Surveyors (RICS) is a global professional body for those working in the Built Environment, Construction, Land, Property and Real Estate. The RICS was founded in London in 1868. It works at a cross-governmental level, and aims to promote and enforce the highest international standards in the valuation, management and development of land, real estate, construction and infrastructure.

Founded as the Institution of Surveyors, it received a royal charter in 1881, and in 1947 became the Royal Institution of Chartered Surveyors. With a London HQ and regional offices across the United Kingdom, plus international offices, it serves a 113,000-strong membership distributed over nearly 150 countries. The RICS is linked to other national surveying institutions, collaborates with other professional bodies, and, in 2013, was a founder member of a coalition to develop the International Property Measurement Standards (IPMS). It also produces cost information and professional guidance on valuation and other activities.

In September 2021, an independent review exposed poor governance practices at the highest levels of the RICS organisation, prompting the resignations of the president, chief executive, interim chair of the governing council, and chair of the management board, in addition to the earlier resignation of the chief operating officer. The report was labelled an "appalling advert for our profession on the world stage". A subsequent review published in June 2022 demanded a "transformation of the institution carried out at pace".

RICS was founded in London, England, as the Institution of Surveyors after a meeting of 49 surveyors at the Westminster Palace Hotel on 15 June 1868. The inaugural president was John Clutton (who founded Cluttons, a property firm still in business today). The organisation has occupied headquarters on the corner of Great George Street and Little George Street since then. It received a Royal charter as The Surveyors' Institution on 26 August 1881, The charter required RICS to "promote the usefulness of the profession for the public advantage in the UK and in other parts of the world."

The Surveyors' Institution became the Chartered Surveyors' Institution in 1930. In 1946, George VI granted the title "Royal" and in 1947 the professional body became the Royal Institution of Chartered Surveyors.

The RICS (with the CIOB, CIBSE, IstructE and RIBA) was a founder member of the Building Industry Council, today the Construction Industry Council, in 1988.

In March 2025, RICS president Justin Sullivan "agreed to step aside" following criticism of his role as an expert witness in legal case regarding a £32.5 million moth-infested mansion. Sullivan referred himself to the body's standards and regulatory board. Nick Maclean, who is due to take over the presidency in 2026, was appointed as acting president temporarily.

On December 1967 the RICS was granted a coat of arms by the College of Arms:
