Joseph Ansoetegui Shakspeare was an American politician in Louisiana; he served as the elected mayor of New Orleans from 1880 to 1882 and from 1888 to 1892. He previously was elected for one term in the state legislature. He was an iron worker.

The post of Mayor of the City of New Orleans has been held by the following individuals since New Orleans came under American administration following the Louisiana Purchase — the 1803 acquisition by the U.S. of 828,800 square miles (2,147,000 km2) of the French province La Louisiane. In all mayoral elections since 1930, New Orleans has used a two-round system with a preliminary round and a runoff if no candidate reached a majority in the first round. All mayors of New Orleans since 1872 have been Democrats.
