William Radford Coyle (born July 10, 1878) was a Republican member of the United States House of Representatives from Pennsylvania. He represented Pennsylvania’s 30th congressional district and served as a federal legislator during the interwar period. His tenure in Congress placed him among the historical members who helped shape national policy in the late 1920s and early 1930s.

Coyle served three terms in the U.S. House of Representatives, holding office from December 7, 1925, to March 3, 1933. During this time, he sat as a Republican representative for Pennsylvania’s 30th district, participating in the legislative work of Congress over the course of eight years. Although specific committee assignments and legislative initiatives are not detailed in the available record, his service from 1925 to 1933 situates him within a consequential era in American political history, spanning the latter part of the Roaring Twenties and the onset of the Great Depression.
