Sōjutsu (槍術, sometimes incorrectly read as yarijutsu) is the art of fighting with the Japanese spear, yari (槍).

Sōjutsu is typically only a single component of curriculum in comprehensive Japanese koryu schools; for example Tenshin Shoden Katori Shinto-ryu includes spear fighting techiques. Other famous sōjutsu schools are Owari Kan-ryu and Hozoin-ryu .
