Interstate 10 (I-10) is the southernmost cross-country interstate highway in the American Interstate Highway System. It stretches from the Pacific Ocean at State Route 1 (SR 1) (Pacific Coast Highway) in Santa Monica, California, to I-95 in Jacksonville, Florida. This freeway is part of the originally planned Interstate Highway network that was laid out in 1956, and its last section was completed in 1990. I-10 is the fourth-longest Interstate Highway in the United States, following I-90, I-80, and I-40. About one-third of its length is within the state of Texas, where the freeway spans the state at its widest breadth.

Between its west terminus in Santa Monica, California, and the major East Los Angeles Interchange, I-10 is known as the Santa Monica Freeway. The Santa Monica Freeway is also called the Rosa Parks Freeway for the segment beginning at I-405 (the San Diego Freeway), and ending at I-110/SR 110 (the Harbor Freeway). The segment between the East Los Angeles Interchange and the city of San Bernardino, 63 miles (101 km) long, is called the San Bernardino Freeway. Other names exist for I-10. For example, a sign near the western terminus of the highway in Santa Monica proclaims this highway the Christopher Columbus Transcontinental Highway.
