John Wesley Crockett (July 10, 1807 – November 24, 1852), was an American politician who represented Tennessee's Twelfth Congressional District in the United States House of Representatives. It was the same district his father, David Crockett, had represented earlier.
Crockett was born in East Tennessee on July 10, 1807 to David (Davy) Crockett (August 17, 1786 – March 6, 1836) and his first wife, Mary (Polly) Finley (1788–1815). He had one brother named William Finley Crockett and one sister named Margaret Finley (Polly) Crockett. He was educated in the public school system, studied law, and then was admitted to the bar. He began his law practice in Paris, Tennessee. He married Martha Hamilton and they had fourteen children.
Crockett held numerous local and state offices before being elected as a Whig to the Twenty-fifth and Twenty-sixth Congresses; he succeeded Adam Huntsman, the man who had defeated his father in the 1835 election. He served from March 4, 1837 to 10 years later on the same day. Crockett was next elected by the Tennessee General Assembly to be the attorney general for the ninth district of Tennessee, and served from 1841 to 1843.
