The National Institute for Research in Digital Science and Technology (Inria) (French: Institut national de recherche en sciences et technologies du numérique) is a French national research institution focusing on computer science and applied mathematics. It was created under the name French Institute for Research in Computer Science and Automation (IRIA) (French: Institut de recherche en informatique et en automatique) in 1967 at Rocquencourt near Paris, part of Plan Calcul. Its first site was the historical premises of SHAPE (central command of NATO military forces), which is still used as Inria's main headquarters. In 1980, IRIA became INRIA. Since 2011, it has been styled Inria.

Inria is a Public Scientific and Technical Research Establishment (EPST) under the double supervision of the French Ministry of National Education, Advanced Instruction and Research and the Ministry of Economy, Finance and Industry.

Inria has nine research centers distributed across France (in Bordeaux, Grenoble-Inovallée, Lille, Lyon, Nancy, Paris-Rocquencourt, Rennes, Saclay, and Sophia Antipolis) and one center abroad in Santiago de Chile, Chile. It also contributes to academic research teams outside of those centers.

Inria Rennes is part of the joint Institut de recherche en informatique et systèmes aléatoires (IRISA) with several other entities.

Before December 2007, the three centers of Bordeaux, Lille and Saclay formed a single research center called INRIA Futurs.

In October 2010, Inria, with Pierre and Marie Curie University (now Sorbonne University) and Paris Diderot University started IRILL, a center for innovation and research initiative for free software.

Inria employs 3800 people. Among them are 1300 researchers, 1000 Ph.D. students and 500 postdoctorates.

Inria does both theoretical and applied research in computer science. In the process, it has produced many widely used programs, such as:
