Hobart Cenotaph is the main commemorative military monument for the Australian state of Tasmania. It is located in the capital Hobart in a prominent position on the Queens Domain, on a small rise overlooking the city and River Derwent. The Cenotaph sits directly above what was once the location of the Queens Battery.

A cenotaph is an empty tomb or a monument erected in honour of a person or group of people whose remains are elsewhere. It can also be the initial tomb for a person who has since been reinterred elsewhere. Although the vast majority of cenotaphs honour individuals, many noted cenotaphs are instead dedicated to the memories of groups of individuals, such as the lost soldiers of a country or of an empire.
