Joubertina is a small town in the Kou-Kamma Local Municipality, Sarah Baartman District of the Eastern Cape province of South Africa.

Having secured a portion of the farm Onzer, in between the villages of Krakeel and Twee Riviere (both founded in 1765), a property development was launched there under the initiative of the Dutch Reformed Church.

As the sale of erven around a newly erected church building gradually got underway in 1907, the future town was named in honour of W A Joubert, minister of the Dutch Reformed Church in Uniondale between 1878 and 1893.

[2] Joubertina is located on the R62 road in the Langkloof valley, approximately 5 km west of Twee Riviere, near the western extreme of the Eastern Cape.

The town has a station on the narrow gauge Avontuur Railway.
