Overbeck's Museum and Garden is an Edwardian house and 2.75 hectare (7 acre) garden situated in Sharpitor, Salcombe, Devon, England. It is named after its last private owner Otto Christop Joseph Gerhardt Ludwig Overbeck (1860–1937). The house is now divided between museum and YHA youth hostel.
The museum houses displays of some of Overbeck's inventions and collections of stuffed animals, and exhibitions of model sailing ships and various nautical and shipbuilding tools and effects. There are display photographs of boats and shipwrecks (such as the Herzogin Cecilie). A room in the middle of the house, one of whose entrances is a secret door concealed in the wooden panelling of the room outside, contains a display of dolls' houses, amongst which is placed by staff "Fred the friendly ghost" for child visitors to discover. The museum contains a Polyphon — a large musical box which plays music encoded as holes punched in large sheet-metal discs. There is a collection of discs of popular melodies of the day which are played from time to time during the day when the museum is open. There is also a collection of photographs by Edward Chapman who worked in and photographed Salcombe — including the building of the first house on the site — during the early 20th Century. The photographs have been reprinted from the original plates by Chapman's son and his grandson, Chris Chapman, who continues the family photography business in Plymouth. Although the route to Overbeck's is challenging and has been described as 'Alp d'Huez on an English scale'  a cream tea from the tea room offers ample compensatory calorific content.
The original building on the site was a small villa "Sharpitor" erected by Salcombe builder Albert Stumbles. This was bought in 1901 by Edric Hopkins, who also bought 2 acres (8,100 m2) more of land, creating terraces and planting exotic specimens on the sheltered site. In 1913 the property was bought by Mr and Mrs Vereker who demolished the original house and had the present one built. Otto Overbeck acquired the house in 1928 and lived there until his death in 1937. Wishing the house to be used after his death as "a public park and museum and a Hostel for Youth" Overbeck bequeathed it to the National Trust on condition it be used as such and not as a brothel as so many in the surrounding area became.
