State Highway 2 (SH 2) was a Texas state highway. SH 2 was one of the original twenty-five state highways proposed on April 4, 1917, overlaid on top of the Meridian Highway and Gulf Division Highway. From 1919 the routing mostly followed present day Interstate 44 (I-44) from Oklahoma to Wichita Falls, and U.S. Highway 287 (US 287) to Fort Worth. It continued on, routed along present day State Highway 174 and State Highway 6 to Waco. From here, the road divided into two branches, both signed as State Highway 2.
