Nicolas Thérèse Benoît Frochot (20 March 1761 - 29 July 1828) was a senior French civil servant and conseiller d'État, as well as the first holder of the office of Prefect of the Seine.
Born in Dijon into a middle-class family, his father was Jean Etienne, who wore "the oratorian collet for seven years"[1] before becoming advocate to the parliament of Dijon in 1754.
Nicolas' mother was Antoinette Geneviève Charpy.
[2] In 1785 he married Denise Petit (1757–1832), daughter of a notary and royal provost at Aignay-le-Duc, who he succeeded.
The marriage made him brother-in-law to Claude-Auguste Petit de Beauverger.
