John Strother Pendleton (* March 1, 1802 in Culpeper, Virginia; † November 19, 1868 ) was an American politician and diplomat. Between 1845 and 1849 he represented the state of Virginia in the U.S. House of Representatives.
John Pendleton enjoyed a good education. After a subsequent law degree in 1824 and its recent approval as a lawyer, he started in Culpeper to work in this profession. At the same time he embarked on a political career. Between 1830 and 1833, and again from 1836 to 1839 he sat in the House of Representatives from Virginia. He was a member of the Whig party. Between 1841 and 1845 he was the successor of Richard Pollard American ambassador in Chile.
In the congressional elections of 1844 Pendleton was the ninth constituency of Virginia in the U.S. House of Representatives in Washington DC chosen, where he became the successor of Samuel Chilton on March 4, 1845. After a re-election he was able to complete in Congress until March 3, 1849 two legislative sessions. These were shaped by the events of the Mexican-American War.
From 1851 to 1854 was Pendleton envoy to Argentina, where he was followed by William A. Harris. In this capacity, he provided along with the U.S. representatives in Brazil, Robert Cumming Schenck, a trade agreement with the countries of Paraguay and Uruguay. After his return, he worked in agriculture. John Pendleton died on November 19, 1868 near Culpeper.
