The Former Middlesex Sessions House is a building on Clerkenwell Green in the London Borough of Islington in London, England. It was built in 1780 for the Middlesex Quarter Sessions of the justices of the peace, replacing nearby Hicks Hall which had fallen into disrepair. The new sessions house also was for some time known as "Hicks Hall". The Sessions House served as the main judicial and administrative centre of Middlesex until the creation of Middlesex County Council and the London County Council in 1889.
