Joseph Bernard Shannon (born March 17, 1867) was a Democratic member of the United States House of Representatives from Missouri. He represented Missouri’s 5th Congressional District and served as a Representative in Congress from December 7, 1931, to January 3, 1943. Over the course of his tenure, Shannon completed six terms in the U.S. House of Representatives.

Serving as a member of the Democratic Party, Shannon’s congressional career was centered on representing the interests of his Missouri constituents during a period that spanned much of the Great Depression and the early years of World War II. Although specific committee assignments, legislative initiatives, and additional offices are not detailed in the available record, his continuous service from 1931 to 1943 reflects a sustained role in national legislative affairs. Shannon left office as a former member of Congress after his final term concluded on January 3, 1943.
