The little finger or pinkie, also known as the baby finger, fifth digit, or pinky finger, is the most ulnar and smallest digit of the human hand, and next to the ring finger.

A pinky ring is any ring worn on the pinky, or little finger, of either hand. A pinky ring may have special significance conferred by the wearer's office or professional association, but may also may be worn purely for fashion. Signet rings, which hold their own meaning, are often worn on the pinky.
