The Etorofu-class escort ships (択捉型海防艦, Etorofu-gata kaibōkan) were a group of fourteen kaibōkan escort vessels built for the Imperial Japanese Navy during World War II. Eight of the fourteen ships were sunk during the war. The class was also referred to by internal Japanese documents as the "Modified A-class" coastal defense vessel (甲型海防艦, Kō-gata kaibōkan).
