Langebaanweg is a town on the southwest coast of South Africa, in Western Cape Province.

Langebaanweg has been an important mining center, with its main minerals consisting of phosphorites, primarily calcium phosphate.

The mining uncovered fossils dating from the late Miocene and early Pliocene, approximately 5 million years ago.

Fossil species found there include invertebrates and also a type of rhinoceros, as well as a mousebird and a diving petrel.
