Pierre Paul Nicolas Henrion, baron de Pansey (28 March 1742 – 23 April 1829) was a French jurist and politician.

Pierre Paul Nicolas Henrion de Pansey was born on 28 March 1742 in Tréveray, Meuse, near to Ligny in Lorraine.

Henrion objected that he did not want to leave the Court of Cassation, but Napoleon assured him that he could stay, and he would only be asked to give verbal advice to the emperor.

[11] As minister he released citizens who had been arbitrarily detained in prison, and suppressed the provostal courts and customs tribunes.

[14] During the Hundred Days (20 March to 8 July 1815) when Napoleon returned from exile, Henrion remained at the Court of Cassation.

[2] In 1822 Henrion published du pouvoir municipal et des Biens communaux, exploring the nature of public and private authority.
