Sciences Po Aix (French pronunciation: [sjɑ̃s po ɛks]), also referred to as Institut d'Études Politiques d'Aix-en-Provence ([ɛ̃stity detyd pɔlitik dɛks ɑ̃ pʁɔvɑ̃s]), is a Grande École of political studies located in Aix-en-Provence, in the South of France. It is associated with Aix-Marseille University and is part of a network of ten Institut d'études politiques, also known as IEP's.

Sciences Po Aix is renowned on a national level for its law studies as well as its defense, geopolitics and international security programs.

Sciences Po Aix was established in 1956 by jurist and law professor Paul de Geouffre de La Pradelle. The school is the direct heir of the École Libre des Sciences Politiques, created by Émile Boutmy in 1872 in response to a need for political stability following the fall of the Second Empire and the birth of the new French Third Republic in 1870.

In September 2007, Philippe Séguin (1943–2010), then President of the Court of Audit (in French Cour des comptes), was elected President of the Administration Council, succeeding Jean-Paul Proust (1940–2010), Minister of the Principality of Monaco. In July 2010, the then French Minister of Economics, who went on to become the International Monetary Fund's director and the current president of the European Central Bank, Christine Lagarde, was elected President of the Administration Council of the school, from which she had graduated in 1977 and had been a board member since 2008.

Sciences Po Aix's main campus is housed in a hôtel particulier, classified as a historical building (monument historique) and designed by architect Georges Vallon in 1734. The building is located on the Place de l'université ("Town square of the university"), opposite the Cathédrale Saint-Sauveur on rue Gaston de Saporta in Aix-en-Provence.

The building previously housed the Faculty of Law of Aix-Marseille University where personalities like Portalis, Adolphe Tiers and painter Paul Cézanne studied.

Sciences Po institutes are Grandes Écoles, French institutions of higher education that are separate from, but parallel and connected to the main framework of the French public university system. Similar to the Ivy League in the United States, Oxbridge in the UK, or C9 League in China, Grandes Écoles are elite academic institutions that admit students through an extremely competitive process. The selection rates at these schools are often under 10%. Former students frequently go on to occupy elite positions within the government, public administration, and corporate firms in France.

Although these institutes are more expensive than public universities in France, Grandes Écoles typically have much smaller class sizes and student bodies, and many of their programs are taught in English. International internships, study abroad opportunities, and close ties with government and the corporate world are a hallmark of the Grandes Écoles. Many of the top ranked schools in Europe are members of the Conférence des Grandes Écoles (CGE), as are the Sciences Po institutions. Degrees from Sciences Po are accredited by the Conférence des Grandes Écoles and awarded by the Ministry of Higher Education and Research (French: Ministère de l’Enseignement supérieur et de la Recherche).

The institute is modeled on the former École Libre des Sciences Politiques, and as such, Sciences Po specializes in political science, but uses an interdisciplinary approach to education that provides student generalists with the high level of grounding in skills that they need in History, Law, Economic Sciences, Sociology, Political science and International relations, enriched by specialization in years 4 and 5, after a 3rd year either on a professional placement in France or overseas or alternatively studying at a foreign university. The third year of the curriculum is a year of mobility abroad, and students have the choice, they can spend two semesters in a foreign university, one semester in a university and one semester internship or they also have the opportunity to spend two semesters as a trainee. The academic course lasts five years, and it is a three-year undergraduate programme and a two-year graduate programme and the primary diploma is a master's degree.

Sciences Po Aix have concluded, to date, 142 exchange partnerships with different universities around the globe, allowing Sciences Po students to study in a foreign country during their third year which is mandatory. All continents of the world are represented, there are partnerships in the United States (Wellesley College, Loyola University Chicago, Arizona State University, Florida International University...), in Canada (University of Montreal, University of Ottawa) in South America (University of Buenos Aires, Federal University of Rio de Janeiro, in Africa (Rhodes University), in Asia (Shanghai International Studies University, Hankuk University of Foreign Studies in Seoul, Waseda University in Tokyo), in Oceania (University of New South Wales in Sydney, University of Canterbury in New Zealand) and also in Europe (Free University of Berlin, LUISS University in Roma, Middlesex University in London).
