Jan Joosten van Lodensteyn (or Lodensteijn; 1556–1623), known in Japanese as Yayōsu (耶楊子), was a Dutch navigator and trader.

Jan Joosten was a native of Delft and one of the first Dutchmen in Japan, and the second mate on the Dutch ship De Liefde, which was stranded in Japan in 1600. He remained in Japan and served as a diplomatic advisor and interpreter to the Tokugawa shogunate on trade and economic matters. He was also engaged in the shuinsen (朱印船, lit.'red seal ship') trade in Asia.

The current name of the area around Tokyo Station in Japan, Yaesu, derives from his Japanese name Yayōsu.
