Bosch (Dutch pronunciation: [bɔs]) was a West Frisian island in the Wadden Sea.

It was situated off the coast of present-day Groningen in the Netherlands, between the islands of Schiermonnikoog and Rottumeroog.

[2] Bosch disappeared in the Christmas Flood of 1717.

[1] A shoal named Boschplaat was the remnant of the island, which merged into Rottumerplaat in 1959.
