Hornsey was a parliamentary constituency covering what is now the Hornsey district of North London. It returned one Member of Parliament (MP) to the House of Commons of the Parliament of the United Kingdom from the 1885 general election until it was abolished for the 1983 general election. It was then largely replaced by the new Hornsey and Wood Green constituency. The constituency was originally created as a division of the Parliamentary County of Middlesex, and comprised the parishes of Finchley and Hornsey.
