Capel Sound is a suburb on the Mornington Peninsula in Melbourne, Victoria, Australia, 61 km (38 mi) south of Melbourne's central business district, located within the Shire of Mornington Peninsula local government area.

[1] A distinguishing landmark feature of Capel Sound is the Tootgarook Swamp, the largest example left of a shallow freshwater marsh in the Port Phillip bay region.

Proponents hoped a name change would distance the town from being seen as only an economically disadvantaged suburb of nearby Rosebud.

On 15 September 2016, Mornington Peninsula Shire Council officially changed the name from Rosebud West to Capel Sound.

[4] The new name was derived from an 1836 survey chart of the area, and was already in use by local businesses such as The Capel Sound Shopping Village.
