John Young Brown was an American attorney and politician. He was a state representative for nearly three decades, serving one term as speaker of the Kentucky House of Representatives and as majority floor leader during the term of Governor Edward T. Breathitt. He was elected to one term in the U.S. House of Representatives from March 4, 1933, to January 3, 1935, to an at-large seat elected statewide on a general ticket. He was an unsuccessful candidate for the Democratic nomination for Governor of Kentucky in 1939 and the unsuccessful candidate for the United States Senate in 1946 and 1966. He was a member of the Democratic Party.

John Young Brown was an American politician from the U.S. Commonwealth of Kentucky who represented the state in the United States House of Representatives and served as its 31st governor. Brown was elected to the House of Representatives for three non-consecutive terms, each of which was marred by controversy. He was first elected in 1859, despite his own protests that he was not yet twenty-five years old, the minimum age set by the Constitution for serving in the legislature. The voters of his district elected him anyway, but he was not allowed to take his seat until the Congress' second session, after he was of legal age to serve. After moving to Henderson, Kentucky, Brown was elected from that district in 1866. On this occasion, he was denied his seat because of alleged disloyalty to the Union during the Civil War. Voters in his district refused to elect another representative, and the seat remained vacant throughout the term to which Brown was elected. After an unsuccessful gubernatorial bid in 1871, Brown was again elected to the House in 1872 and served three consecutive terms. During his final term, he was officially censured for delivering a speech excoriating Massachusetts Representative Benjamin F. Butler. The censure was later expunged from the congressional record.
