The Division of Denison was an Australian electoral division in Tasmania, before being replaced by the Division of Clark as part of a 2016–17 redistribution.

The Division of Tasmania was an Australian electoral division covering Tasmania. The five-member statewide seat existed from the inaugural 1901 election until the 1903 election. Each elector cast one vote. Unlike most of the other states, Tasmania had not been split into individual single-member electorates. The other exception was the seven-member Division of South Australia. The statewide seats were abolished at a redistribution conducted two months prior to the 1903 election and were subsequently replaced with single-member divisions, one per displaced member, with each elector now casting a single vote.
