The Guardian Assurance Company was a British insurance company based in London and formed in 1821 to offer both life and fire insurance. Through a combination of organic growth and acquisition it became one of the leading insurance companies. It operated as a mutual organization, meaning that it was owned by its policyholders rather than by shareholders. In 1968 it merged with Royal Exchange to form Guardian Royal Exchange.
