The article is devoted to a comparative analysis of two forms of international co-operation of local government units - Euroregion, whose origins in Poland date back to the early 1990s of the twentieth century and the new form of cooperation which is a European grouping of territorial cooperation introduced into the Polish law by the Act of 7 November 2008 on a EGTC . Step by step all the elements characteristic of these forms are examined, such as the legal basis, the creation process and the associated formal requirements, objectives, targets, funding sources, the procedure of liquidation as well as the benefits that each of these forms bring to their members. Finally, in a concise manner, all the advantages and disadvantages of the Euroregion and the EGTC are summarized, with emphasis on the fact that it is difficult to indicate the form of international cooperation that would be most appropriate and most advantageous to the local government units.
