The Mobile River is located in southern Alabama in the United States. Formed out of the confluence of the Tombigbee River and Alabama River rivers, the approximately river drains an area of of Alabama, with a Drainage basin extending into Mississippi, Georgia, and Tennessee. Its drainage basin is the fourth-largest of primary stream drainage basins entirely in the United States. The river has historically provided the principal navigational access for Alabama. Since construction of the Tennessee-Tombigbee Waterway, it also provides an alternative route into the Ohio River watershed.
The Tombigbee and Alabama River join to form the Mobile River approximately northeast of Mobile, along the county line between Mobile and Baldwin counties. The combined stream flows south, in a winding course. Approximately downstream from the confluence, the channel of the river divides, with the Mobile flowing along the western channel. The Tensaw River, a bayou of the Mobile River, flows alongside to the east, separated from as they flow southward. The Mobile River flows through the Mobile-Tensaw River Delta and reaches Mobile Bay on the Gulf of Mexico just east of downtown Mobile.
Biodiversity
The Mobile River Basin historically supported the greatest
biodiversity of
freshwater snail species in the world (Bogan et al. 1995), including six genera and over 100 species that were
endemism to the Mobile River Basin. During the past few decades, publications in the scientific literature have primarily dealt with the apparent decimation of this fauna following the construction of dams within the Mobile River Basin and the inundation of extensive shoal (a shallow place in a body of water) habitats by impounded waters (Goodrich 1944, Athearn 1970, Heard 1970, Stein 1976, Palmer 1986, Garner 1990).

The James M. Barry Electric Generating Plant, owned by Alabama Power, has a leaking unlined fly ash pit located "on land that lies within a hairpin crook of the Mobile River." For this reason the river has been described as the third most endangered river in the United States.
Crossings
This is a list of
and other crossings of the Mobile River from
Mobile Bay upstream to its source at the confluence of the
Tombigbee River and
Alabama River rivers. Proposals for a new bridge to carry Interstate 10 over the river have been debated for several years. Currently the Alabama Department of Transportation is conducting an environmental impact study for such a crossing and into the widening of the
Jubilee Parkway, which carries Interstate 10 over
Mobile Bay. The location of this bridge is of great debate with some parties pushing for a crossing south of the current tunnels while others are opposed to anything south of the Cochrane–Africatown USA Bridge.
