Samuel Jaudon (May 14, 1796 – May 31, 1874) was a 19th-century American banker and businessman who was best known for his work as cashier and agent of the Bank of the United States from 1832 to 1837.

In 1835, Jaudon sold the Bainbridge estate bonds and invested the money in the Delaware and Raritan Canal Company.

[7] In 1837-1838, Jaudon served as a director of the Wilmington and Susquehanna Railroad, one of the four companies that created the first rail link from Philadelphia to Baltimore.

[8] Jaudon resigned from the railroad's board in January 1838,[9] and traveled to London to try to sell various U.S. securities on behalf of the now-private Bank of the United States.

[10] Among his endeavors, he sought in March to secure a $400,000 loan for the PW&B-connected Harrisburg, Portsmouth, Mountjoy and Lancaster Railroad.

[6] On December 10, 1841, Jaudon, along with Biddle and John Andrews, were indicted by a grand jury on charges of defrauding the Bank's stockholders of $400,000 in 1836 and trying to cover it up through fraudulent recordkeeping in 1841.

[13] In 1855, Jaudon was secretary of the Texas Pacific Railway Company based in New York, but which sought to build a railroad with land grants from the Mississippi River.

[14][15] The American Civil War interrupted the project, which ultimately succeeded after Jaudon's death as the Texas and Pacific Railway under Jay Gould.
