Young Europe (Italian: Giovine Europa; German: Junges Europa; Polish: Młoda Europa) was an international political association founded in 1834 by Giuseppe Mazzini on the model of Young Italy. It was composed of the national societies of Young Italy, Young Poland and Young Germany, which, independent in their own spheres, acted in common, through a central committee, for the furthering of the principles of liberty, equality, and humanity in Europe. The headquarters of the society were in Switzerland, where, in 1835–36, the organization of a French society, Young France, was brought about. The activity of the society speedily aroused the opposition of the Swiss authorities, who expelled many of its members from the country.

Young Ireland was a contemporary nationalist organisation which, though not affiliated with Young Europe, took its name in reference to Young Italy and Young Europe.
