纪州犬是原产于日本和歌山县原产的一种日本犬。纪州犬在日本犬里为中型犬，于昭和九年（1934年）继秋田犬与甲斐犬之后被指定为天然纪念物。

纪州犬相当适合当作家犬，在日本犬里饲养数量也仅次于柴犬。

该犬种是在纪伊国（今日本和歌山县到三重县熊野地方）的山岳地带，即纪伊山地周边被用来协助狩猎野猪等工作的土狗品种固定后所培育出来的犬种，现在在近畿地方南部也有许多将纪州犬当作家犬的爱好者。不过，也有继续将纪州犬培育来狩猎野猪的专门训练所。

The Kishu(紀州犬,Kishū-Inu), sometimes called Kishu Ken or Kishu Inu, is a Japanese breed of dog, developed there for thousands of years. It is descended from ancient medium-sized breeds and named after the Kishu region, now Mie Prefecture and Wakayama Prefecture. This breed is similar to the Hokkaido, Shikoku and the Kai Ken. Sometimes it is mistaken for the white variant of Hokkaido because of very similar appearance. The Japanese originally used this breed of dog for boar and deer hunting. Like the Shiba, they are often quiet. Kishu will stalk prey quietly rather than bark.
