Metaline Falls is a town in Pend Oreille County, Washington, United States.

The settlement of Metaline Falls was founded in 1900, with most of its residents then employed by the Mammoth and Morning lead-zinc mines.

The Lehigh Portland Cement Co. plant was soon built, taking advantage of the region's limestone deposits.

George Kubota, Sr., the patriarch of a Japanese-American family who ran a hardware store in town, was arrested and imprisoned by the FBI in Spokane.

The editors of the Metaline Falls newspaper and the majority of residents in town protested the arrest, vouching for the Kubota family's loyalty.

Metaline Falls is home to four of Pend Oreille County's six locations on the National Register of Historic Places.

The Lewis P. Larson House, built in 1910 and designed by Kirtland Cutter is an English cottage style home.

The Metaline Falls School, also designed by Cutter, was built in 1912 in the classical revival style.

The school was abandoned in 1972 and sat unmaintained until 1990 when local residents came together to take care of the historic building, which is now known as the Cutter Theater and serves as a community center.
