Lying approximately between latitudes 60° and 70° N, and longitudes 20° and 32° E, Finland is one of the world's northernmost countries. Of world capitals, only Reykjavik lies more to the north than Helsinki. The distance from the southernmost—Hanko—to the northernmost point in the country—Nuorgam—is 1,160 kilometres (720 mi).

Finland is a country of thousands of lakes and islands—187,888 lakes (larger than 500 m2/0.12 acre) and 179,584 islands. Its largest lake, Saimaa, is the fourth largest in Europe. The area with most lakes is called Finnish Lakeland. The greatest number of islands are to be found in the southwest in the Turku archipelago. Further from the coast lies Ahvenanmaa or Åland (in Swedish) Islands.

Much of the geography of Finland is explained by the Ice Age. The glaciers were thicker and lasted longer in Fennoscandia compared to the rest of Europe. Their eroding effects have left the Finnish landscape mostly flat with few hills and fewer mountains. Its highest point, the Halti at 1,324 metres (4,344 ft), is found in the extreme north of Lapland at the border between Finland and Norway. The highest mountain whose peak is entirely in Finland is Ridnitsohkka at 1,316 m (4,318 ft), directly adjacent to Halti.

The retreating glaciers have left the land with morainic deposits in formations of eskers. These are ridges of stratified gravel and sand, running northwest to southeast, where the ancient edge of the glacier once lay. Among the biggest of these are the three Salpausselkä ridges that run across southern Finland.

Having been compressed under the enormous weight of the glaciers, terrain in Finland is rising due to the post-glacial rebound. The effect is strongest around the Gulf of Bothnia, where land steadily rises about 1 cm a year. As a result, the old sea bottom turns little by little into dry land: the surface area of the country is expanding by about 7 square kilometres (2.7 sq mi) annually. Relatively speaking, Finland is rising from the sea.

Forest covers 86% of the country's area, the largest forested area in Europe. The forest consists of pine, spruce, birch and other species. Finland is the largest producer of wood in Europe and among the largest in the world.

The landscape is covered mostly (75% of land area) by coniferous taiga forests and fens, with little arable land. The most common type of rock is granite. It is a ubiquitous part of the scenery, visible wherever there is no soil cover. Moraine or till is the most common type of soil, covered by a thin layer of humus of biological origin. Podzol profile development is seen in most forest soils except where drainage is poor. Gleysols and peat bogs occupy poorly drained areas.
