Owari, formally written as Owari no Kuni (尾張国) was a former province of Japan that is now the western half of present-day Aichi Prefecture. Its abbreviation is Bishu (尾州).

The capital was Inazawa, in the west of the province. Two of the most famous generals of Japan's Sengoku period, Oda Nobunaga and Toyotomi Hideyoshi, hailed from this province, and Oda had a castle in Kiyosu.
