Theodore C. Link, FAIA, (March 17, 1850 – November 12, 1923) was a German-born American architect and newspaper publisher.

His best known work is in the Richardsonian Romanesque style, specifically the St. Louis Union Station (1894), and the Second Presbyterian Church (1899).

[3] Link immigrated to the United States, arriving in St. Louis in 1873 to work for the Atlantic and Pacific Railroad company.

[4] After a four-year interim as a German-language newspaper publisher in Pittsburgh, Pennsylvania, Link returned to St. Louis just after the turn of the century as one of the architects for the 1904 World's Fair.

"[5] Link died in Baton Rouge while working on the new Louisiana State University campus,[6] and was interred at Bellefontaine Cemetery in St. Louis.
