David Barry Brudnoy (June 5, 1940 – December 9, 2004) was an American talk radio host in Boston from 1976 to 2004. His radio talk show aired on WBZ radio. He was known for espousing his libertarian views on a wide range of political issues, in a manner that was courteous. Thanks to WBZ's wide signal reach, he gained a following from across the United States as well as Canada. On December 9, 2004, he succumbed to Merkel cell carcinoma after it had metastasized to his lungs and kidneys.
