Baia is a commune in Tulcea County, Northern Dobruja, Romania.

The commune includes five villages: In 1953, archaeological excavations on a site along the Lake Golovița, near Baia, led to the discovery of a new Middle Neolithic culture, named after the commune.

Further research has shown that the culture, with Mediterranean origins, extended across Dobruja and North-Eastern Bulgaria.

The culture's most notable artefact is an anthropomorphic statuette in terra cotta, known as The Thinker, which was discovered at Cernavodă.
