Berrigan Shire is a local government area in the southern Riverina region of New South Wales, Australia. The Shire lies on the New South Wales State border with Victoria formed by the Murray River. The Shire is adjacent to the Newell and Riverina Highways. The Shire is a mainly agricultural region, with dairying, cattle raising, woolgrowing and cropping the main activities. The vast majority of the Shire is irrigated. Tourism is another major activity, concentrated on the river towns of Tocumwal and Barooga.

Local government is the third-level of government in Australia, administered with limited autonomy under the states and territories, and in turn beneath the federal government. Local government is not mentioned in the Constitution of Australia, and two referendums in 1974 and 1988 to alter the Constitution relating to local government were unsuccessful. Every state/territory government recognises local government in its own respective constitution. Unlike the two-tier local government system in Canada or the United States, there is only one tier of local government in each Australian state/territory, with no distinction between counties and cities.
