Cymbuliidae is a family of pelagic sea snails or "sea butterflies", marine gastropod mollusks in the superfamily Cymbulioidea.

Instead of an external calcareous shell, they possess a pseudoconch, consisting of conchioline, a cartilaginous tissue. The mantle and the gill have disappeared as well. They breathe through the skin. They prefer warm water.

Cymbuliidae are found in all marine waters between -54 and 55°N.
