Terebellum derives from a Latin word meaning borer or auger. In English, it can refer to:
- Terebellum, a genus of sea snails in the family Seraphsidae
- Terebellum, a group of stars in the constellation Sagittarius
The Terebellum, by Ptolemy called τετράπλευρον (/tetrápleuron/), is a quadrilateral of stars in the constellation Sagittarius. It is formed of four 4th magnitude stars, all within two degrees of each other:
- Omega Sagittarii, at the northeast corner.
- 59 Sagittarii or b Sagittarii, at the southeast corner.
- 60 Sagittarii or A Sagittarii, at the northwest corner.
- 62 Sagittarii or c Sagittarii, at the southwest corner.
The stars are not gravitationally bound to each other as they are at different distances from the Earth.
Terebellum is a genus of sea snails, marine gastropod mollusks in the family Strombidae, the true conchs.

A slim but shapely mollusc known as Terebellum or augur, to mention another conceited little disturber of your meditations, stands on its spire in the sand, and screws as you tread, cutting, a delightfully symmetrical hole in the sole of your foot, and retaining the core--perfect as that of a diamond drill.
