Murrumbidgee is a former electoral district of the Legislative Assembly in the Australian state of New South Wales, named after the Murrumbidgee River.
It existed in various forms from the creation of the Legislative Assembly in 1856 until its abolition in 2015.
Until its abolition, Murrumbidgee and Parramatta were the only electorates to have existed continuously since the first Legislative Assembly election in 1856, although before 1913 it was called The Murrumbidgee.
Voters cast a vote for each vacancy.
Between 1920 and 1927, it absorbed parts of Lachlan and Ashburnham and elected three members under proportional representation.
