Cobba is a goddess, probably but not definitively Germanic, worshipped in what is now the Netherlands.
She is accompanied in Utrecht by the goddess Borvoboendoa who is honored at a healing spring; this companionship may suggest a healing aspect to Cobba as well.
Cobba received votive and dedicatory offerings from her worshippers; otherwise little is known of the specifics of her cult.
Cobba’s name is of uncertain origin and could derive from either Celtic or Germanic sources. Most of the little information I’ve seen has leaned in the direction of a Germanic origin.
Cobba is known from an inscription found at Utrecht in the Netherlands.
