Thymiaterium was an ancient Carthaginian colony in present-day Morocco. It was founded by Hanno the Navigator on his journey of exploration beyond the Pillars of Hercules and then southwest along the African coast as detailed in The Periplus of Hanno, as translated from a Greek version by Wilfred H. Schoff.
According to Hanno, he founded the colony, the first of his journey, two day's sail past the Pillars of Hercules. Schoff, citing a scholar named C. Miiller, identified it with the town of Mehedia, currently known as Mehdya.
The location of Thymiaterium is also given at Mehedia in the Atlas of Ancient & Classical Geography.
