Ordu-Baliq is in a grassy plain called the Talal-khain-dala steppe, on the western bank of the Orkhon River in the Khotont sum of the Arkhangai Province, Mongolia, 16 km northeast of the Khotont village, or 30 km north-to-northwest of Kharkhorin. The Orkhon emerges from the gorges of the Khangai Mountains and flows northward to meet the Tuul River, which has on its upper reaches the current capital of Mongolia, Ulan Bator.
