Somerhill House (/ˈsʌmərhɪl haʊs/) is a Grade I listed Jacobean mansion situated near Tonbridge, Kent, United Kingdom. It was built for The 4th Earl of Clanricarde in 1611–13. The estate was sequestrated by Parliament in 1645, and restored to its rightful owner in 1660. The building had become derelict by the mid-eighteenth century but was later restored. Somerhill was painted by Turner in 1811. It was bought by a member of the Goldsmid family in 1849 and greatly extended between 1879 and 1897, making it the second largest house in Kent, after Knole House, Sevenoaks.
