St. Matthew's Cathedral, Episcopal cathedral in Laramie, United States.

St. Matthew's Cathedral is a Gothic Revival Episcopal church designed by New York architect William Halsey Wood. It is built of native sandstone quarried nine miles northeast of Laramie, has a cruciform plan, and its bell tower and spire rise 118 feet (36 m) above ground, making it the highest cathedral in the United States.

Construction began in 1892 under Bishop Ethelbert Talbot's direction and was completed in 1896, reflecting the town's early development. The building rose during the era of railway expansion and served as a symbol of the established community in the growing mountain region.

The cathedral is the seat of the Diocese of Wyoming, created by the 1967 General Convention of the Episcopal Church; its first diocesan convention met here on January 30, 1968. The close also holds the Deanery, Hunter Hall and a First World War Memorial Cross. The tower's 11 bells were cast by Meneely & Co. of Watervliet, New York.

The building is easily accessible from downtown and offers a relaxed setting for exploration. Visitors should bring warm clothing, as the elevation and mountain air can feel cool even in warmer months.

The cathedral's pipe organ, E.M. Skinner Opus 523, was installed in 1925 with four manuals, 51 ranks and 3,111 pipes. Its console was replaced in 1998 by a rebuilt 1928 Casavant console from Opus 1275, reworked by Morel & Associates.
