Jean-Nicolas Pache (1746 – November 18, 1823) was a French politician.

Pache was born in Paris, of Swiss parentage, the son of the concièrge of the hotel of Marshal de Castries. He became tutor to the marshal's children, and subsequently first secretary at the ministry of marine, head of supplies (munitionnaire général des vivres), and comptroller of the king's household. After spending several years in Switzerland with his family, he returned to France at the beginning of the Revolution.

He was employed successively at the ministries of the interior and of war, and was appointed on September 20, 1793 third deputy suppliant of Paris by the Luxembourg section. Thus brought into notice, he was made minister of war on October 3, 1792

Pache was a Girondist himself, but aroused their hostility by his incompetence. He was supported, however, by Marat, and when he was superseded in the ministry of war by Beurnonville (February 4, 1794) he was chosen mayor by the Parisians. In that capacity he contributed to the fall of the Girondists, but his relations with Hébert and Chaumette, and with the enemies of Robespierre led to his arrest on May 10 1794. He owed his safety only to the amnesty of October 25, 1795. After acting as commissary to the civil hospitals of Paris in 1799, he retired from public life, and died at Thin-le-Moutier on November 18, 1823.
