罗托卡特语(Rotokas)是个由大约4000名布干维尔省(布干维尔是巴布亚新几内亚共和国东部的一个岛屿)居民所使用的语言。目前已知罗托卡特语至少有三个方言，它们分别为：中央罗托卡特方言(Central Rotokas，又称为Rotokas Proper)、爱塔罗托卡特方言(Aita Rotokas)和皮皮派亚方言(Pipipaia)，中央罗托卡特方言有着极端小型的发音数量，而且有着或许是全世界字母数量最少的现代字母书写系统。

Rotokas is an East Papuan language spoken by some 4,000 people in Bougainville, an island to the east of New Guinea, part of Papua New Guinea. According to Allen and Hurd (1963), there are three identified dialects: Central Rotokas ("Rotokas Proper"), Aita Rotokas, and Pipipaia; with a further dialect spoken in Atsilima (Atsinima) village with an unclear status Central Rotokas is most notable for its extremely small phonemic inventory and for having perhaps the smallest modern alphabet.
