Pieter Stadnitski (2 April 1735 – 29 November 1795) was a Dutch broker and financier who invested in the United States, including federal and state debt, canal companies, and land speculation, especially the Holland Land Company. He was the first to bring speculative American bonds - issued by the Congress to finance the American War of Independence - to the Amsterdam market in 1787. Stadnitski was co-founder in 1789 and from 1793 head of a small group of Amsterdam trading houses that bought land in the states of New York and Pennsylvania on a large scale. His role was considered significant by Thomas Jefferson.
