The Kerch Strait is a strait in Eastern Europe. It connects the Black Sea and the Sea of Azov, separating the Kerch Peninsula of Crimea in the west from the Taman Peninsula of Russia's Krasnodar Krai in the east. The strait is to wide and up to deep. The most important harbor, the Crimean city of Kerch, gives its name to the strait, formerly known as the Cimmerian Bosporus. It has also been called the Straits of Yenikale after the Yeni-Kale fortress in Kerch.
Taman, the most important settlement on the Taman Peninsula side of the strait, sits on Taman Bay, which is separated from the main Kerch Strait by the Chushka Spit to the north and the former Tuzla Spit to the south; the Tuzla Spit is now Tuzla Island, connected to the Taman Peninsula by a 2003 Russian-built dam, and to mainland Crimea by the Crimean Bridge opened in 2018. A major cargo port is under construction near Taman.

The straits are about long and are wide at the narrowest and separate an eastern extension of Crimea from Taman, the westernmost extension of the Caucasus Mountains. In antiquity, there seem to have been a group of islands intersected by arms of the Kuban River (Hypanis) and various sounds which have since silted up. The Romans knew the strait as the Cimmerian Bosporus (Cimmerius Bosporus) from its Greek name, the Cimmerian Strait (Κιμμέριος Βόσπορος, Kimmérios Bosporos), which honored the Cimmerians, nearby steppe nomads. In ancient times the low-lying land near the Strait was known as the Maeotic Swamp.
The Cimmerian Bosporus in ancient times was regarded as separating Europe from Asia, just as the Thracian Bosporus did. Most geographers, such as Posidonius, Strabo (Geographica 11.7.4), and Ptolemy, considered the boundary between Europe and Asia to be the river Tanais (Don), which flows into the Sea of Azov from the north; an alternative view, found in the poet Cornelius Gallus was that it was the river Hypanis (Kuban), which flows into the Sea of Azov from the east, close to the Cimmerian Bosporus.
