Starodub-on-the-Klyazma was a prominent urban centre of Russian Opolye from the 12th until the 14th century. Like so many towns in the vicinity, it was named by migrating population for a southern city they came from, in this case, for Starodub in Severia. The town was on the bank of the Klyazma River about twelve kilometres from the modern-day Kovrov. Nowadays, the village of Klyazminsky Gorodok stands on the spot.
