U.S. Route 90 or U.S. Highway 90 (US 90) is an east–west major United States highway in the Southern United States. Despite the "0" in its route number, US 90 never was a full coast-to-coast route. It generally travels near Interstate 10 (I-10) and passes through the southern states of Texas, Louisiana, Mississippi, Alabama, and Florida. US 90 also includes part of the DeSoto Trail between Tallahassee and Lake City, Florida.

With the exception of a short-lived northward extension to US 62/US 180 near Pine Springs, Texas, that existed for less than one year, its western terminus has always been at Van Horn, Texas; this is an intersection with I-10 Business (formerly US 80) just north of an interchange with I-10. Its eastern terminus is at Florida State Road A1A in Jacksonville Beach, Florida, three blocks from the Atlantic Ocean.

On August 29, 2005, a number of the highway's bridges in Mississippi and Louisiana were destroyed or damaged due to Hurricane Katrina, including the Bay St. Louis Bridge, the Biloxi Bay Bridge, and the Fort Pike Bridge which have been replaced.
