Carna refers to two distinct women from Roman mythology. The modern English word carnal is derived from this name.

• Carna was a nymph who lived where Rome would eventually be. Janus fell in love with her and gave her power over door hinges and handles. As a goddess, she was known as Cardea.
• Carna was a Roman goddess who presided over the heart and other organs. Her festival took place on June 1.
