Agaronia gibbosa, also known as the Olive Shell, is a species of sea snail and a marine gastropod mollusk belonging to the family Olividae.

The shell of this species measures 1.5 to 3 inches in length. The shell is heavy and gibbous, with a notably callous columella, particularly thickened at the upper part. The spire is also robustly thickened. The shell is primarily cream-colored, with the body whorl featuring zigzags and reticulations that range from ash-gray to orange and chocolate. The fasciole is yellowish and maculated with brown. The columella and the interior of the aperture are whitish.

Agaronia gibbosa varies in shape, yet larger specimens are often recognized among other Agaronia by their prominent spire callus and bulbous form, as opposed to the more common narrow and bullet-like shape. Naturally, Agaronia gibbosa shells are typically blotched green with a striped yellow band near the siphonal canal, although an all-yellow morph also exists. Frequently traded in the shell market, it's usual for the shell's outer layer to be polished off, exposing the underlying brownish-black color.

These species inhabit the Indian Ocean, commonly found along the coasts of the Indian subcontinent, Thailand, and Indonesia.
