Italy and Algeria maintain a longstanding diplomatic relationship that began shortly after Algeria's independence in 1962. The two countries share a common geographical space that has fostered growing cooperation over the years, strengthened by converging interests in the fields of energy, economics, and migration. Italy has long been, and continues to be, one of Algeria’s key European partners—not only due to its historic collaboration in the hydrocarbons sector, but also through continuous political dialogue and joint efforts in infrastructure, education, and culture. Over the years, the two states have signed a number of bilateral agreements covering areas of fundamental importance for strengthening institutional and economic ties. In addition to these bilateral treaties, both Italy and Algeria are parties to relevant multilateral conventions that enhance legal certainty, promote economic cooperation, and enable mutual recognition of civil and commercial decisions.

Below is a list of the main bilateral agreements between Italy and Algeria, as well as key multilateral conventions to which both countries are signatories, of particular relevance to operators and institutions engaged in cross-border relations between the two legal systems.
