The lydion (Greek λύδιον; plural lydia) was an ancient Greek vase shape. The shape may have been of Egyptian derivation.^[1]

As indicated by its name, the lydion originated in Lydia, but was also adopted by potters in Greece. A small spherical perfume container, lacking handles, it was especially popular in East Greece. The vessel stood on a narrow, relatively high foot, cylindrical or conical in shape. The neck could be of varying length; it met the body at an acute angle. The lip was horizontal. Usually, the lydion was decorated with stripes. In Athens, it was only produced rarely; figural decoration was even rarer.
