Baaiduinen is a village on the Frisian Wadden Sea island of Terschelling in the Netherlands.

[1] Baaiduinen is surrounded by the much older hamlets of Kinnum, Kaart (Kaard) en Horp.

Baaiduinen is the youngest village on Terschelling and has only been recognized as a separate settlement in the 19th century.

North of Baaiduinen is a polder landscape named het Hoge Land ("the highlands").

Tourism has replaced dairy farming as the main source of income and most farms have been rebuilt to accommodate tourists.
