The Carbuncle Cup is an architecture prize, given annually, originally by the magazine Building Design, and since 2024 by The Fence, to "the ugliest building in the United Kingdom completed in the last 12 months". It was intended to be a humorous response to the prestigious Stirling Prize, given by the Royal Institute of British Architects.
