Electoral district of County of Durham

The Electoral district of County of Durham was an electorate of the New South Wales Legislative Council at a time when some of its members were elected and the balance were appointed by the Governor. It was named after Durham County, which lies on the north side of the Hunter River.

It was created by the 1843 Electoral Districts Act and initially returned one member. It returned two members with the expansion of the Council in 1851 to 54, 18 to be appointed and 36 elected. 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 electorate of Durham
