Hafnia is a genus of Gram-negative, facultatively anaerobic, rod-shaped bacteria in the family Hafniaceae.

H. alvei is a commensal of the human gastrointestinal tract and not normally pathogenic, but may cause disease in immunocompromised patients. It is often resistant to multiple antibiotics, including the aminopenicillins.

The name comes from Hafnia, the Latin name for Copenhagen.

Hafnia alvei is used as a lactic ferment by the dairy industry and more recently as a probiotic[2][3] included in a dietary supplement product.
