The Icelandic Forest Service (Icelandic: Skógræktin [ˈskouː(ɣ)ˌraixtɪn]) (IFS) is a subordinate agency to the Ministry for the Environment and Natural Resources of the Government of Iceland. This governmental institution works not only with and for the government but also for the public and other parties interested. The main subjects are research development, consultation work and the distribution of knowledge and know-how within the Icelandic forest sector. Furthermore, the IFS acts as Iceland's representative body for international forest-related cooperation. The Director of IFS as of 2016 is Mr. Throstur Eysteinsson. The Icelandic Forest Research Mógilsá (Icelandic: Mógilsá, rannsóknasvið Skógræktarinnar) is a research division of the Icelandic Forest Service with headquarters located at Mógilsá [is], near Reykjavík. The head of research is Ms. Edda Sigurdís Oddsdóttir.

For over a century the IFS has had two main obligations, one being the protection and expansion of remaining native birchwoods in the country, the other executing afforestation projects throughout the country for the purpose of commercial forestry. Afforestation projects have been put through on IFS lands in different locations in Iceland. Furthermore, state supported afforestation on farms has in recent decades grown to become the main channel for afforestation activity in Iceland. Within the Icelandic farm afforestation grants scheme, contracts are made with landowners, afforestation plans are drawn up for each participating farm, seedling production and distribution are coordinated, education and extension services are provided and grants are distributed. State funding of farm afforestation grants reached a maximum during 2005-2009 but suffered severe cut-backs after the 2008 financial collapse. Planting is now on the rise again after a decade of stagnation. In recent years, with ever clearer signs of global warming, carbon sequestration has become one of the most important drivers of new afforestation projects in Iceland.

Prior to the deforestation of Iceland in the Middle Ages, some 40% of the land was forested.^[2][3] Today, the country is about 2% forested, with the Icelandic Forest Service aiming to increase that share to 10% through reforestation and natural regrowth.^[4][5][6][7]
