The Birds Directive (more formally known as Council Directive 2009/147/EC on the conservation of wild birds) is a European Union directive adopted in 2009. It replaces Council Directive 79/409/EEC of 2 April 1979 on the conservation of wild birds which was modified several times and had become very unclear. It aims to protect all European wild birds and the habitats of listed species, in particular through the designation of Special Protection Areas (often known by the acronym SPA).

The Birds Directive is one of the EU's two directives in relation to wildlife and nature conservation, the other being the Habitats Directive. The Habitats Directive led to the setting up of a network of Special Areas of Conservation, which together with the existing Special Protection Areas form a network of protected sites across the European Union called Natura 2000.
