The Union Chapel is a Grade II* listed church and music venue in Islington, North London, England, located on Compton Terrace. An example of Victorian gothic architecture, it was designed by James Cubitt, and constructed between 1874 and 1877, with further additions 1877-90, providing an ambitious new Congregationalist Church for Henry Allon. The 'Union' in the name refers to its origins as a joint congregation of Anglicans and non-conformists.
