Sumiyoshi taisha (住吉大社), also known as Sumiyoshi Grand Shrine, is a Shinto shrine in Sumiyoshi ward in the city of Osaka, Japan. It is the main shrine of all the Sumiyoshi shrines in Japan. However, the oldest shrine that enshrines the Sumiyoshi sanjin, the three Sumiyoshi kami, is the Sumiyoshi shrine in Hakata.
It is called "Sumiyoshi-san" or "Sumiyossan" by the locals, and is famous for the large crowds that come to the shrine on New Year's Day for hatsumōde.
Sumiyoshi taisha enshrines the Sumiyoshi tanjin -- Sokotsutsu no Onomikoto, Nakatsutsu no Onomikoto, and Uwatsutsu no Onomikoto -- and Okinagatarashihime no Mikoto (Empress Jingū), and they are collectively known as the "Sumiyoshi Ōkami", the great gods of Sumiyoshi. Another term is "Sumiyoshi no Ōgami no Miya".
It gives its name to a style of shrine architecture known as Sumiyoshi-zukuri.
