Olifantsfontein, also known as Clayville, is a small town on the East Rand in the Gauteng Province of South Africa.

It is located at the north-western corner of the City of Ekurhuleni Metropolitan Municipality, just north of the Thembisa township.

[1] Olifantsfontein is divided into 3 main suburbs, namely Clayville East (the entire area east of the passing Metrorail Line), Clayville Industrial (the entire area south of View Road, with many industrial operations) and Clayville CBD with its extensions (the area north of View Road).

Both roads connect Clayville with Kempton Park in the south and with Pretoria in the north.
