The Institut National Agronomique Paris-Grignon (INA P-G) was a French grande école. It was created in 1971 by merging the Institut national agronomique (Paris) and the École nationale supérieure d'Agronomie de Grignon, thus having a history that goes back to 1826.
INA P-G disappeared as an administrative entity on January 1, 2007, becoming part of AgroParisTech with ENSIA and ENGREF.
