CalPortland Company, or simply CalPortland, is an American corporation that produces cement and other building materials. It was founded in 1891 and claims to be the largest such company in the Western United States.[1] The company was founded in California but today maintains its headquarters in Summerlin, Nevada.[2] Since 1990, it has been owned by Taiheiyo Cement, a Japanese company.

CalPortland's subsidiary in Washington state, Glacier Northwest, was a party to a 2023 Supreme Court decision, Glacier Northwest, Inc. v. Teamsters, that found that the right to strike under the National Labor Relations Act does not preclude lawsuits against the union for actions related to the strike.
