Hikawa Shrine is a Shinto shrine located in Ōmiya-ku, Saitama, Saitama Prefecture, Japan. It is one of the two shrines claiming the title of ichinomiya of former Musashi Province. The main festival of the shrine is held annually on August 1. The district of Omiya, literally "Great Shrine", derives from the special favor shown by Emperor Meiji, who raised Hikawa above all other shrines in the Kantō region. It is the head of a network of approximately 280 Hikawa shrines mostly around the Kantō region.

Ōmiya is one of ten wards of the city of Saitama, in Saitama Prefecture, Japan, and is located in the northeastern part of the city.
