James Miller (1860–1947) was a Scottish architect, recognised for his commercial architecture in Glasgow and for his Scottish railway stations. Notable among these are the American-influenced Union Bank building at 110–20 St Vincent Street; his 1901–1905 extensions to Glasgow Central railway station; and Wemyss Bay railway station on the Firth of Clyde. His lengthy career resulted in a wide range of building types, and, with the assistance of skilled draughtsmen such as Richard M Gunn, he adapted his designs to changing tastes and new architectural materials and technologies.
