Faith is a city in the northeastern corner of Meade County, South Dakota, United States.

[6] The most complete Tyrannosaurus rex skeleton known, Sue, was discovered approximately 15 miles (24 km) northeast of Faith in August 1990.

[7] However, the story of the city as documented in various informal, locally published histories, is that the town was named for Faith Rockefeller, one of the daughters of a major investor in the railroad responsible for founding the town.

[8][9] This is in keeping with the names of other towns on the route of the old railroad (now abandoned), such as Isabel, South Dakota.

[8] Founded as the town at the end of the railroad, Faith was originally the hub of a homestead boom in the period 1910–1920; but the drought conditions of the 1920s that led to the Dust Bowl of the 1930s quickly replaced abnormally wet conditions of the early 20th century, and the harsh winters of the northern plains quickly drove many sodbusters to more hospitable regions.

The town's location allows for ranch families in the area to have schools and stores closer than Sturgis, Fort Pierre, or other regional market towns, but early expectations of steady growth were never realized.

According to the United States Census Bureau, the city has a total area of 1.20 square miles (3.11 km2), all land.

A small reservoir, Durkee Lake, is approximately three miles south and offers a local recreation venue, with its boating, fishing, golf course, beach, and camping.

Durkee Lake receives runoff water from Spook Creek,[11] which is located about 6.2 miles (10 km) south of Faith.

[14] The Faith Municipal Building, designed by U. L. Freed, is listed on the National Register of Historic Places.
