Caleys was a department store in Windsor, Berkshire, England.
For much of the 20th century it was part of department store groups and it acquired royal warrants.
The store was established by John Caley and his wife Mary Ann Caley on 5 April 1823 as advertised in the Windsor Express at the time and remained a family business for over a century, growing into a well regarded department store opposite Windsor Guildhall which is close to Windsor Castle.
On 18 January 2006, John Lewis announced the closure of the store, stating that 'the location, size and layout of the building will always stand in the way of any prospect of a return to profitable trading'.
The site was redeveloped in 2010 with the addition of 2 extra floors to become a multi use site consisting of the Macdonald Windsor Hotel as the major tenant, with a TK Maxx department store and Esquires coffee shop also present.
