Vernon Mount is a ruined Georgian manor house in Cork, Ireland. It was built between the 1780s and early 1790s to designs attributed to Abraham Hargrave. Originally built for the merchant Hayes family, the house was named for Mount Vernon, the home of US president George Washington. Passing through several owners, the house remained largely disused and subject to deterioration from the late 20th century. It was included in the Record of Monuments and Places by the National Monuments Service, and on the Record of Protected Structures for Cork County Council. It remained largely intact until 2016, when a significant fire largely gutted the house, and the building was subsequently listed on the derelict sites register. In 2021, the building was subject to a funding request for stabilisation works due to "risk of collapse".
