The Lovat (Belarusian: Ловаць, romanized: Lovac', IPA: [ˈɫovatsʲ]; Russian: Ло́вать) is a river in Vitebsk Oblast of Belarus, Usvyatsky, Velikoluksky, and Loknyansky Districts, as well as of the city of Velikiye Luki, of Pskov Oblast and Kholmsky, Poddorsky, Starorussky, and Parfinsky Districts of Novgorod Oblast in Russia. The source of the Lovat is Lake Lovatets in northeastern Belarus, and the Lovat is a tributary of Lake Ilmen. Its main tributaries are the Loknya (left), the Kunya (right), the Polist (left), the Redya (left), and the Robya (right). The towns of Velikiye Luki and Kholm, as well as the urban-type settlement of Parfino, are located on the banks of the Lovat.
From the source, the Lovat flows in the southeastern direction along the border between Russia and Belarus, it turns north and enters Pskov Oblast of Russia, crossing the border as Lake Sesito. In this area, the Lowat flows through the lake district, passing, in particular, Lake Vorokhobskoye. Downstrean of Velikiye Luki, in the selo of Podberezye, the Lovat turns northwest and enters Novgorod Oblast. Close to Lake Ilmen, the Lovat shares a river delta with the Pola and the Polist, though technically Polist is counted as a tributary of the Lovat.
