The Market Research Society is a professional body for market research based in London. It was established in 1946 at the offices of the London Press Exchange. It represents the views of its members to government and in the press. Jan Gooding has been the president since 1 April 2017.
In 2015, it jointly ran an inquiry with the British Polling Council into the failings of polling before the British general election of that year. The inquiry found that the failure of polling to correctly predict the result was the result of unrepresentative polling samples.
