Mowich Lake is a lake located in the northwestern corner of Mount Rainier National Park in Washington state at an elevation of {{Convert|4929|ft|m|0}}. The name "Mowich" derives from the Chinook jargon word for deer.{{cite web|title=American Indian Names in and around the Umpqua National Forest|work=Umpqua National Forest|publisher=USFS|url=http://www.fs.fed.us/r6/umpqua/heritage-program/american-indian-names.shtml|archive-url=https://web.archive.org/web/20070312010319/http://www.fs.fed.us/r6/umpqua/heritage-program/american-indian-names.shtml |archive-date=12 March 2007 |url-status=dead}}

Access to the lake is provided by a {{Convert|17|mi|km|0}} long unpaved road which opens to vehicles in mid June to early July. Mowich Lake is also a busy campground during the summer with 30 walk-in tent camping spots. Bathrooms, tables, and trash bins are provided.

From the Mowich campground, hikers can reach the Wonderland Trail, Eunice Lake, Tolmie Peak, Spray Park, and Spray Falls. Old-growth trees, waterfalls, creeks, cliffs, and wildflower meadows are also located in and around the area.

Fishing is generally poor at Mowich Lake because the area is not stocked with fish and no habitat is provided for natural spawning.{{cite book|author=Stienstra, Tom and Stephani|year=2002|title=Foghorn Outdoors Washington Camping: The Complete Guide to More Than 650 Campgrounds|publisher=Avalon Travel Publishing|isbn=1-56691-469-8}}

This body of water was named Crater Lake in 1883 by the geologist Bailey Willis under the belief that it was formed in a volcanic crater, however I. C. Russell later wrote that the land was shaped instead by ice erosion. Willis concurred.{{cite book |title=Mount Rainier: A record of exploration |editor=Edmond S. Meany |editor-link=Edmond S.

Exploring the mountain and its glaciers, 1896 |pages=166–167, 306–307 |date=1916 |publisher=Macmillan }} Correspondents to the U.S. Board on Geographic Names (BGN) proposed Mowich to avoid ambiguity with the well-known Crater Lake to the south in Oregon. Mowich Lake was designated the official name by the BGN in 1919. The name of its outflow Crater Creek remained unchanged.{{cite gnis|1523454|name=Mowich Lake}}
