U.S. Highway 175 (US 175) is a 111.0-mile (178.6 km) east-west United States Numbered Highway located completely within the state of Texas. It comes very close to meeting its parent route, US 75, but decommissioning and rerouting in Downtown Dallas leaves it short a couple of miles. Before the decommissioning of US 75 south of downtown Dallas in favor of Interstate 45 (I-45), US 175 met US 75. US 175's western terminus is in Dallas at I-45. The highway's eastern terminus is in Jacksonville at an intersection with US 69.

Much of the US 175 corridor (from I-20 in Balch Springs to US 69 in Jacksonville) is part of TxDOT's network of evacuation routes in the event of a hurricane.^[2] TxDOT also considers the highway an alternative to using I-20 to travel to and from Dallas-Fort Worth, and feels the corridor is an important connection for students to get to Stephen F. Austin State University in Nacogdoches, as well.^[3] Besides its hurricane evacuation route status, US 175 is considered part of the National Highway System,^[4] the Texas Trunk System^[5] (later revised to just the portion between Mabank and Jacksonville^[6]), and is also included in the state's highway freight network.^[7]

Of all the three-digit U.S. Highways located within Texas, US 175 is the shortest.^[1]
