The Corinthian Chamber Orchestra is an amateur orchestra based in London, United Kingdom. Formed in 1995 under the musical direction of conductor Alan Hazeldine, it rapidly developed into one of the best orchestras of its kind and its membership consistently includes the very best amateur players available. The orchestra's high standards are maintained by an insistence on thorough preparation and a professional attitude to performance.
The orchestra promotes around six of its own concerts per year (normally at St James's Church, Piccadilly) and also performs in concerts promoted by other organisations. It has played for charity concerts in aid of Cancer Research UK, the North London Hospice, Youth At Risk and The Refugee Council and has made regular appearances with the North London Chorus.
