Jacobsbaai is a settlement in West Coast District Municipality in the Western Cape province of South Africa.
Jacobsbaai was originally founded as a small town on the farmland registered as 109 Jacobsbaai. The name is said to have evolved form the Frenchman Jacques Titius. He was a colonial trader in the West Coast. Tietiesbaai is also named after him and Jacobsbaai has a street called Titius. Another explanation for the name is that the English king entrusted the piece of land to a local known as ‘Jacob.’
