The Great Wagon Road was a colonial American thoroughfare transiting the Great Appalachian Valley from Pennsylvania to North Carolina and from there to Georgia. The Great Wagon Road was the heavily traveled main route for settlement of the Southern United States, particularly the ''back country''. This was the area that received many German and Scots-Irish immigrants in the 18th century. The Scots-Irish and English from the Northern Border area were the largest group of immigrants from the British Isles before the American Revolution.
