Henri Paul Nénot (27 May 1853 – 1934) was a noted French architect.

Nénot was born in Paris. After his initial training in an architectural workshop, he entered the studio of Charles-Auguste Questel at the École Nationale Supérieure des Beaux-Arts while also working for various architects, including Charles Garnier. He was in residence at the Villa Medici 1878–1881.

In 1882 Nénot began his career, during which he was appointed architect of the Sorbonne, which remains his great work, as well as designing other university buildings in Paris and a number of private residential and commercial buildings. In 1895 he was elected department chair for architecture in the Académie des beaux-arts. His last position was Director General for the architecture of the Palace of Nations in Geneva, where he died in an accident.
