The Treaty of Mozhaysk (also Moshaisk or other transliterations of Можайск) was a Danish-Russian treaty concluded on 7 August 1562, during the Livonian War. While not an actual alliance, the treaty confirmed the amicable Dano-Russian relation and obliged the parties to not support the other parties in the war, to respect each other's claims in Old Livonia, and to grant free passage to each other's merchants.
