Highway M14 is a Ukrainian international highway (M-highway) connecting Odesa to the Russian border east of Mariupol, where it continues into Russia as the A280.

[1] The M14 is a major transnational corridor and along with the M16 combines into the southern branch of European route E58 in Ukraine (another one in Zakarpattia).

It runs along the coastal line of Black and Azov seas, connecting two major ports of Ukraine in Odesa and Mariupol.

Since 2014, a part of the road in eastern Ukraine has been under the control of the separatist Donetsk People's Republic.

During the 2022 Russian invasion of Ukraine, Russia took direct control of areas of the road in Donbas, Kherson Oblast and Zaporizhzhia Oblast.
