Mogilev or Mahilioŭ (Russian: Могилёв, Mogilyov [məɡʲɪˈlʲɵf]; Belarusian: Магілёў, Mahilioŭ, [maɣʲiˈlʲou̯], Yiddish: מאָלעוו, Molev) is a city in eastern Belarus, on the Dnieper River, about 76 kilometres (47 miles) from the border with Russia's Smolensk Oblast and 105 km (65 miles) from the border with Russia's Bryansk Oblast.

Belarus began using its own country code +375 in 1995, replacing the +7 international country code inherited from the Soviet Union. The local numbering plan was inherited from the Soviet Union and remains with few changes.

В. Ф. Копытин утверждал, что Могилёв первоначально возник как сторожевой город-крепость в окружении ремесленных и сельских поселений xi—xii веков.
