The Victoria History of the Counties of England, commonly known as the Victoria County History or the VCH, is an English history project which began in 1899 with the aim of creating an encyclopaedic history of each of the historic counties of England, and was dedicated to Queen Victoria. In 2012 the project was rededicated to Queen Elizabeth II in celebration of her Diamond Jubilee year. Since 1933 the project has been coordinated by the Institute of Historical Research in the University of London.

The Institute of Historical Research (IHR) is a British educational organisation providing resources and training for historical researchers. It is part of the School of Advanced Study in the University of London and is located at Senate House. The institute was founded in 1921 by A. F. Pollard.
