Canarium urceus is a species of sea snail, a marine gastropod mollusk in the family Strombidae, the true conchs.

The anterior canal is often well formed and acute in nature, being slightly reflected dorsally.

The spire is always nodulated with the knobs varying from acute in some populations to more rounded and less pronounced in others.

The columella is midnight black, sometimes with some traces of deep plum that flush the posterior.

This species is restricted to Singapore and The South China Sea (Maxwell 2020).
