Tsurumi-ku (鶴見区) is one of the 18 ku (wards) of the city of Yokohama in Kanagawa Prefecture, Japan.

Tsurumi-ku is located in eastern Kanagawa Prefecture, in the northeast corner of the city of Yokohama.

However, for security reasons, the actual settlement was established at neighboring Yokohama (present day Naka-ku).

The Namamugi Incident, which led to the 1863 Anglo-Satsuma War, occurred in what is now part of Tsurumi Ward.

Sōji-ji, the head temple of the Sōtō sect of Zen Buddhism relocated to Tsurumi from Ishikawa Prefecture in 1911.

The area suffered greatly again during World War II, and was completely devastated during the massive Yokohama air raid of May 29, 1945.

Tsurumi Ward is a regional commercial center and bedroom community for central Yokohama and Tokyo.

Soji-ji was rebuilt in Yokohama in 1911, after it burned down at its old location in Wajima City, Ishikawa Prefecture.
