Del Valle (/ˌdɛl ˈvæli/ del VAL-ee) is a suburb of Austin and part of the Austin–Round Rock–San Marcos Metropolitan Statistical Area.
It is an unincorporated area in southeastern Travis County, Texas, United States. It has no local government of its own and no official boundaries. But Austin has annexed portions, including the site of Austin-Bergstrom International Airport in 1990. After that, most recently in 2013, the city added more Del Valle territory to the east (8 to 13 miles southeast of downtown Austin).
The 2010 census estimates the population to be 17,139.
