The Houghton Duchess is a British-made folding plate camera from the early twentieth century, produced by the London firm Houghton (later Houghtons Ltd / Houghton-Butcher). It was sold as a portable amateur instrument in the era when sheet-film and plate folders dominated the consumer market.

Sales data for the Duchess at UK auction is very thin: the single recorded hammer result on file is £156 from October 2017, so any current 'worth' figure today should be treated as indicative rather than a reliable median. At saleroom level, value is highly condition-sensitive — bellows integrity, shutter function and completeness of the lens and plate holders drive what a clean example sells for.
