Electoral district of Counties of Roxburgh, Phillip and Wellington

The Electoral district of Counties of Roxburgh, Phillip and Wellington and from 1851, Roxburgh and Wellington, was an electorate of the partially elected New South Wales Legislative Council, created for the first elections for the Council in 1843. The electoral district included the western counties of Roxburgh, Phillip, Wellington County. Polling took place at Montefiores, Mudgee, Bathurst and Hartley. The County of Phillip was removed from the district with the expansion of the Council in 1851 and became part of the Counties of Phillip, Brisbane and Bligh.

At all four elections, there was only one candidate who was therefore elected unopposed. In 1856 the unicameral Legislative Council was abolished and replaced with an elected Legislative Assembly and an appointed Legislative Council. The district was represented by the Legislative Assembly electorates of Roxburgh and Wellington (County).
