Etchu (越中国; Etchū-no kuni) was an old province in central Honshu, on the Sea of Japan side. It bordered Echigo, Shinano, Hida, Kaga, and Noto Provinces. The area is today Toyama Prefecture.
The ancient provincial capital was Takaoka, but by the Sengoku period the area was usually held by lords from neighboring provinces like Echigo and Kaga.
