The Thesmar-Cheryk High Road was a high road between the cities of Thesmar and Cheryk, in the South March of the Republic of Siddarmark.

In the Year of God 896, the Royal Dohlaran Army marched to Thesmar on this road during its invasion of the South March, but was ambushed and defeated by the Imperial Charisian Army in what became known as the Battle of Thesmar. (MTAT)
