Interstate 69 (I-69) is a partially completed Interstate Highway in the United States currently consisting of ten disjointed parts with an original continuous segment from Indianapolis, Indiana, northeast to the Canada–US border in Port Huron, Michigan, at 355.8 miles (572.6 km). The remaining separated parts are variously completed and posted or unposted parts of an extension southwest to the Mexican border in Texas. Of this extension—nicknamed the NAFTA Superhighway because it would help trade with Canada and Mexico spurred by the North American Free Trade Agreement—five pieces near Corpus Christi, Houston, northwestern Mississippi, Memphis, and Evansville have been newly built or upgraded and signposted as I-69. A sixth segment of I-69 through Kentucky utilizing that state's existing parkway system and a section of I-24 was established by federal legislation in 2008, but only a portion is signposted. A section of the previously existing Western Kentucky Parkway from Eddyville to Nortonville was approved and signposted in late 2011, with the Pennyrile Parkway between Nortonville and Henderson being signed as I-69 in 2015, and the Purchase Parkway between Mayfield and Calvert City signed in July 2018. This brings the total length to about 720 miles (1,160 km).

The proposed extension evolved from the combination of Corridors 18 and 20 of the National Highway System as designated in the Intermodal Surface Transportation Efficiency Act of 1991, but the federally recognized corridor also includes connecting and existing infrastructure, including I-94 between Chicago and Port Huron and several spurs from I-69. Among these proposed spurs are an extension of I-530 from Pine Bluff, Arkansas, an upgrade of U.S. Route 59 (US 59) from Texarkana, Texas, and a split in southern Texas to serve three border crossings at Laredo, Pharr, and Brownsville.

In August 2007, I-69 was selected by the United States Department of Transportation as one of six Corridors of the Future, making it eligible for additional federal funding and streamlined planning and review. This funding has since been withheld, causing some states to suspend construction indefinitely.
