Janjina is a village and a municipality located right in the center of the Pelješac peninsula, in the Dubrovnik-Neretva County, Croatia.

The village of Janjina includes a tiny fishing harbor and a hamlet called Zabreže (Behind the hill), the name describing its geographic situation.

It is divided into five parts: Gornje Selo (The Upper Village) comprising Lovrovići, which together with Bara are known to exist from the 4th century AD.

The meaning of Janjina remains uncertain, but the local belief is that it derives from the female Christian name Janja, a Slavic form of the Hebrew Johanna.
