Athoracophoridae, common name the leaf-veined slugs, are a family of air-breathing land slugs, terrestrial pulmonate gastropod mollusks in the order Stylommatophora, the stalk-eyed snails and slugs. Many of the species have an attractive pattern on their dorsal surface which resembles the veins in a leaf, hence the common name.

Athoracophoridae is the only family in the superfamily Athoracophoroidea.

Leaf-veined slugs live on the various land masses and islands in the south-west Pacific area. In te reo Māori, leaf-veined slugs are known as putoko ropiropi.

The scientific name Athoracophoridae is derived from prefix "a-", that means "without" and from a Greek word "θωραχοφὁρος" (thorachoforos), that means "breastplate". This is a reference to the fact that the mantle in these slugs is small and not well delineated; it does not have the obvious, saddle-shaped or breast-plate-shaped appearance that it does in most other land slug groups.
