The School for Advanced Studies in the Social Sciences (French: École des hautes études en sciences sociales, EHESS) is a graduate grande école and grand établissement in Paris focused on academic research in the social sciences. The school awards Master and PhD degrees alone and conjointly with the grandes écoles École normale supérieure, École polytechnique, and École pratique des hautes études.
Originally a department (Section VI) of the École pratique des hautes études, created in 1868 with the purpose of training academic researchers, the EHESS became an independent institution in 1975. Today its research covers social sciences, humanities, and applied mathematics. Degrees and research in economics and finance are awarded through the Paris School of Economics.
