Ottosdal is a small farming town located in the central North West Province of South Africa. Situated at an altitude of 1,479 meters, it lies along the branch railway line from Makwassie. The town was officially registered in 1917 and was named in honor of Gerhardus Petrus Otto.
The community is primarily engaged in agriculture, with local farmers producing grains such as maize, sunflowers, and peanuts, as well as raising cattle, sheep, pigs, dairy cows, and chickens. Additionally, a significant pyrophyllite mine is located nearby on the farm Gestoptefontein.
Ottosdal originated from the establishment of a Dutch Reformed Church parish in 1913, which included a church building on the farm Korannafontein. The town is also notable as the birthplace of "Die Baas," who was born there in 1952.
