Samuel Seabury (February 22, 1873 – May 7, 1958) was an American lawyer and politician from New York.
Seabury is famous for dedicating himself to a campaign against the corrupt Tammany dominance of New York City politics.
He later presided over the extensive 1930–32 investigations of corruption in the New York City municipal government, which became known as the 'Seabury Hearings'.
Seabury became a Georgist after reading Progress and Poverty.
