{{nihongo|Nishi-ku|西区|Nishi-ku}} was a ward in Hamamatsu, Shizuoka, Japan, located in the southwest corner of the city. It is bordered by Naka-ku, Kita-ku, Minami-ku, and the city of Kosai. The 3rd largest ward of Hamamatsu in terms of area, much of the ward is still rural, with farms and rice fields.

Nishi-ku was created on April 1, 2007 when Hamamatsu became a city designated by government ordinance (a "designated city").

Nishi-ku is served by Maisaka Station and Bentenjima Station on the Tōkaidō Main Line railway.
