The Stockholm School of Economics, SSE (Swedish: Handelshögskolan i Stockholm, HHS) is one of Europe's leading business schools. SSE is a privately owned business school that receives 78% of its financing from private sources and 22% from the Swedish government. SSE offers bachelors, masters and MBA programs, along with highly regarded PhD- and extensive Executive Education programs (customized and open programs).

The Stockholm School of Economics was founded in 1909 on private initiative as a response to rapid industrialization and a growing need for well educated businessmen and company managers and has maintained close ties with the business community ever since. The foundation followed a substantial donation in 1903 by Knut Agathon Wallenberg. The name handelshögskola (roughly "college of commerce") was a parallel to the German term Handelshochschule, used by a number of German institutions started in the years before, commencing with Handelshochschule Leipzig in 1898. The term högskola was at this time also established for specialised higher educational institutions outside the universities, such as the Royal Institute of Technology, (Kungl.) Tekniska högskolan, which bore that name from 1877.
