Avoca was an electoral district of the Legislative Assembly in the Australian state of Victoria from 1859 to 1889. It was based in northern Victoria. It was defined by the 1858 Electoral Act as:

Commencing at the source of the River Avoca in the Main Dividing Range ; thence northwards by that river and by a line bearing north to the River Murray ; thence by the River Murray to the River Loddon; thence south-wards by the River Loddon to McNeil's Creek; thence by McNeil's Creek to the Main Dividing Range; and thence westerly by the Main Dividing Range to the commencing point aforesaid, including the parish of Tarnagulla.

McNeil's Creek now known as Bet Bet Creek.

In April 1889, a new district, Talbot and Avoca, was created.
