A transboundary protected area (TBPA) is a protected area that spans boundaries of more than one country or sub-national entity, where the political border sections that are enclosed within its area are abolished. This includes removal of all human-made physical boundaries, such as fences, allowing free migration of animals and humans within the area. A boundary around the area may however be maintained to prevent unauthorised border crossing. Such areas are also known by terms such as transfrontier conservation areas (TFCAs) or peace parks. The Global Transbounday Protected Areas Network cites five different types of TBPAs as follows:

• Two or more contiguous protected areas across a national boundary
• A cluster of protected areas and the intervening land
• A cluster of separated protected areas without intervening land
• A trans-border area including proposed protected areas
• A protected area in one country aided by sympathetic land use over the border
