The Tunisian diaspora refers to people of Tunisian origin living outside that country. It is the direct result of the strong rate of emigration which Tunisia has experienced since its independence in 1956. In the 1960s and 70s, the favourable economic situation in France and Europe increased the phenomenon. The beginning of the 1980s saw the clear development of a Tunisian community in Europe as a result of the large number of people.

In 2014 the number of Tunisians residing abroad was numbered at 1,282,371 individuals, of which 87% were living in Europe. However, this official figure appears to be lower than reality because of the inadequate recording of migration statistics. Thus it is not rare to discover a single data point represents all the members of a family or to discover duplicates. Among the citizens which are underrepresented in the statistics are the third generation in France (according to one estimate, only one in ten of these have been recorded) and the children of mixed-nationality parents. The illegal immigrants (very numerous in Italy for example) are by definition not included in the official statistics.

750,000 have settled in France - one of the most important foreign communities in the country - and two thirds of them hold double citizenship. They are concentrated mostly in the large cities (40% in Paris, 12% in Lyon and 8% in Marseille, with smaller communities in Nice, Bordeaux, Toulouse, Strasbourg, and Lille). Sonia Mabrouk connects this clumping phenomenon with the urban origin of the Tunisian migrants (Tunis and the littoral), but also with the nature of the different waves of migration. Thus the 1970s mainly saw the arrival of migrants from the south of Tunisia. These settled in the Rhône Valley and at Paris which offered the greatest number of opportunities for employment and created connections with their places of origin, which subsequently encouraged other migrants to settle in the same places. According to INSEE, 1.4% of children born in 2011 in Metropolitan France (i.e. 11,466 of 792,996) had a father born in Tunisia, with the greatest proportion in the departments of Alpes-Maritimes (8.6%), Var (4.5%), Seine-Saint-Denis (3.9%), Rhône (3.7%), Val-de-Marne (3.4%), and Bouches-du-Rhône (2.4%).

In Germany Tunisians are dispersed throughout the country in many medium-sized cities and villages especially in the states Lower Saxony, North Rhine Westphalia, Bavaria, Hessen and Baden Württemberg. The Köln-Bonn region is has the most significant number of Tunisians with about 7.000 Tunisians residing in the two cities and their surroundings. The Braunschweig Region , which has a significant presence of Tunisians, estimating 5.850 Tunisians, with most of the population concentrated in the cities Braunschweig, Wolfsburg and Salzgitter. Braunschweig is a partner city of Sousse and Wolfsburg is a partner city of Jendouba, making the area a significant location for Tunisians to migrate to in Germany. The Rhine-Ruhr region has a population of around 4.500 Tunisians. The Rhine-Main Metropolitan has 3.200 Tunisians with majority of the community in Frankfurt, Wiesbaden and Offenbach. Another region with a sizeable Tunisian community is Rhine-Neckar with Ludwigshafen and Mannheim having the most number of tunisians in this region. The cities Cologne, Berlin, Braunschweig, Bonn, Hamburg and Munich have the largest Tunisian communities in Germany.

There are 110,385 Tunisians in the other Arab countries, 44,195 in North America, 3359 in Subsaharan Africa and 2365 in Asia (excepting the Arab countries); 514 Tunisians are accounted for in Australia.

Statistics of the Office of Tunisians Abroad show more than 128,000 Tunisian families in Europe with a concentration in France and Germany. Young Tunisians (less than 16 years of age) represent 25% of the Tunisian community abroad. Thus there is currently a rejuvenation of the Tunisian diaspora which is now in its third generation. Women represent nearly 26% of the total community. In France, their percentage is estimated at 38.2%. The portion of the diaspora who are over 60 years old is around 7%.

Originally, the largest part of the Tunisians in Europe worked in sectors requiring minimal qualifications. In effect the migrants of the 1960s and 70s were less educated (mostly farmers or manual labourers).

Subsequently, the majority of Tunisians settled in France have worked in the service sector (hotels, restaurants or retail) or have headed small businesses. In 2008, Tunisia became the first of the Maghreb countries to sign a management agreement concerning the flow of migrants, at the impetus of President Nicolas Sarkozy: it provides easy access for almost 9,000 Tunisian students enrolled in French institutions, but also almost 500 titres de séjour (residency permits) for highly qualified individuals so that they can acquire experience in France, valid for a maximum of six years. In the Arab World the Tunisian population is mostly made up of very highly qualified individuals while labourers and other unskilled individuals form the majority in Asian countries like India, Pakistan, and Afghanistan. In 2025, a note from the Immigration Observatory in France notes that integration, particularly economic, is difficult, as are the expulsions of Tunisian undocumented immigrants.
