犬神（又名狗神）是一种日本妖怪，施术者可以召唤它降灾于人，或守护自身或家族的安全。原指死后被人操纵留在世间徘徊不去的狗灵，是西日本分布最广的妖怪。

在九州的大分县东部、岛根县、从四国的东北部乃至高知县一带有着根深柢固的迷信观念。也有人说有狐出没的四国，是犬神的原产地的说法。此外，犬神信仰遍布的范围，从岛根县西部到山口县、包括九州整个地区，最远甚至连鹿儿岛县的萨南诸岛也找得到犬神信仰的踪迹。犬神在当地也叫做「インガメ」（ingame）、「イリガミ」（irigami）。

Inugami(犬神, lit. "dog god"), similar to Shikigami, are a class of beings in Japanese mythology belonging to the spirits known as Kami. They are generally created by Onmyōji.

Japanese folklore describes Inugami as zoomorphic, or anthropomorphic, dog-like beings, often similar to werewolves. They are also said to be masters of black magic.
