State Highway 56 is a state highway in the U.S. state of Texas that runs through Grayson and Fannin Counties in North Central Texas. This highway was designated in 1974 to replace U.S. Highway 82 when it was rerouted north of Whitesboro and Sherman. SH 56 has been extended further since then as the US 82 bypass continued to be extended north of Bonham and Honey Grove.

Through Sherman, SH 56 operates on a pair of one-way streets, Lamar (eastbound) and Houston (westbound).

Previous routes

SH 56 was originally designated by 1926 through the northwestern Panhandle, coinciding with the future route of U.S. Highway 54. Construction was completed by 1938, when the SH 56 designation was dropped in favor of US 54.
