Shewsbury is the name that was used for an unincorporated town in Jefferson Parish, Louisiana, along the Mississippi River about 1 mile upriver from the border of the city of New Orleans. The name came into use in the 19th century, and largely fell out of use towards the end of the 20th century, when surrounding communities of unincorporated Jefferson grew together as a suburb of New Orleans. The area formerly known as Shrewsbury is now generally considered to be part of Jefferson, Louisiana.

Shrewsbury Louisiana is referred to in the Rhythm & Blues song Shrewsbury Blues by Dave Bartholomew.
