西滨鹬（学名：Calidris mauri）为鹬科滨鹬属下的一个种。

The western sandpiper (Calidris mauri) is a small shorebird.

Adults have dark legs and a short, thin, dark bill, thinner at the tip. The body is brown on top and white underneath. They are reddish-brown on the crown. This bird can be difficult to distinguish from other similar tiny shorebirds, especially the semipalmated sandpiper. This is particularly the case in winter plumage, when both species are plain gray. The western sandpiper acquires winter plumage much earlier in the autumn than the semipalmated sandpiper.
