George Mortimer Bibb (October 30, 1776 – April 14, 1859) was an American lawyer and politician and the seventeenth United States Secretary of the Treasury.

At the time of Bib's death, his body servant Willis was auctioned in Washington DC, near the White House.

[4] In 1811 he was elected to the United States Senate from Kentucky and served until 1814 when he again returned to Lexington to work as a lawyer.

[5] He was chancellor of the Louisville Chancery Court from 1835 through 1844 and in 1844 became President John Tyler's fourth United States Secretary of the Treasury serving through 1845.

Bibb's Annual Report on the State of the Finances for 1844 consisted of an elaborate compilation of statistics detailing the financial history of the nation since 1789.

In addition, he presented a solid argument for the establishment of a "sinking fund," accumulated through regular deposits and used to pay the interest and principal on the national debt.
