State Highway 175 (SH 175) is a state highway in the U.S. state of Texas that runs from Montague to Nocona in Montague County.
The southern terminus of SH 175 is at an intersection with SH 59 and FM 1806 in the unincorporated community of Montague. The route heads north on a two-lane undivided road through rural areas before crossing into Nocona.
