Osborne House, 19th century mansion in North Geelong, Australia

Osborne House is a mansion built in 1858 in North Geelong for squatter Robert Muirhead, designed by Melbourne architects Webb and Taylor. The house itself now accommodates various community groups, while the abandoned stables house the Geelong Maritime Museum and the Geelong Memorial Brass Band.

Osborne House was built in 1858 for the local squatter Robert Muirhead, who named it after Queen Victoria's summer residence on the Isle of Wight and commissioned the Melbourne architects Webb and Taylor. Muirhead lived there until his death in 1862, and the house was sold the following year. From 1919 to 1924 it housed the Royal Australian Navy's six J-class submarines.

The house takes its name from Osborne House on the Isle of Wight, Queen Victoria's summer residence, chosen by Robert Muirhead. The stables now house the Geelong Maritime Museum and the Geelong Memorial Brass Band, while the house itself is used by various community groups.

Osborne House stands on Swinburne Street in North Geelong, inland from Corio Bay rather than on the shoreline. The house itself holds community groups, while the former stables house the Geelong Maritime Museum and the Geelong Memorial Brass Band. The site is best reached by car or train, as the naval college was sited here for its rail access.

The naval college that opened here on 1 March 1913 was opened by Governor-General Lord Thomas Denman, who arrived by torpedo boat while 200 guests came by train from Melbourne. Its first class of 28 cadets was picked from 137 candidates, and the college moved to Jervis Bay in 1915.
