国民公会（法语：Convention nationale）是法国大革命时期的最高立法机构，在法兰西第一共和国的初期拥有行政权和立法权。

1792年8月10日，巴黎起义军占领杜伊勒里宫，立法议会宣布废黜法国国王路易十六，在普选基础上成立国民公会。1792年9月20日，国民公会开幕，当选议员749名。其中吉伦特派为右翼，约160人，山岳派（因议员坐在议会厅较高位置而得名）为左翼，约140人，而人数最多的为中间派，也称平原派或沼泽派（因议员坐在议会厅较低位置得名）。国民议会初期的代表人物有：让-保罗·马拉、乔治·雅克·丹东和雅各宾俱乐部马克西米连·罗伯斯庇尔。

The National Convention (French:Convention nationale) was a single-chamber assembly in France from 20 September 1792 to 26 October 1795 (4 Brumaire IV under the Convention's adopted calendar) during the French Revolution. It succeeded the Legislative Assembly and founded the First Republic after the insurrection of 10 August 1792. The Legislative Assembly decreed the provisional suspension of King Louis XVI and the convocation of a National Convention which was to draw up a constitution. At the same time it was decided that deputies to that convention should be elected by all Frenchmen twenty-five years old or more, domiciled for a year and living by the product of their labor. The National Convention was therefore the first French assembly elected by universal male suffrage, without distinctions of class.
