有田焼(日语:有田焼ありたやき Arita-yaki)是日本九州的原肥前国烧制的一种瓷器,是日本最具代表性的陶瓷[1]。该瓷器在古代被大量出口至欧洲,其烧制工艺在日本一直延续至今。有田烧的鼻祖李参平万历朝鲜战争移居日本朝鲜陶瓷匠。[2][3]作品依制造时期、样式等大致区分成初期伊万里古九谷样式柿右卫门样式金襕手等。另外,还有别系统,仅作为献上用的极上品烧制的作品,藩窑锅岛藩的“锅岛样式”、上纳皇室的“禁里样式”。

Arita-Ware (japanisch: 有田焼, Hepburn: Arita-yaki) ist eine allgemeine Bezeichnung für japanisches Porzellan, das in der Gegend um die Stadt Arita in der ehemaligen Provinz Hizen im Nordwesten der Insel Kyūshū hergestellt wird. Es ist auch als Hizen-Ware (肥前焼, Hizen-yaki) nach dem weiteren Gebiet der Provinz bekannt. In diesem Gebiet wurde die große Mehrheit des frühen japanischen Porzellans, insbesondere des japanischen Exportporzellans, hergestellt.
