This is a list of rivers of Finland. Listing begins with rivers flowing into the Baltic sea, from the north, that is from the Swedish border. Tributaries are listed down the page in an upstream direction.

Water flows from Finland directly to the Baltic Sea, which is divided here into the Gulf of Bothnia and Gulf of Finland, and the Archipelago Sea between them. Some rivers flow to Russia, ending either to Gulf of Finland or to the White Sea, and a few to the Arctic Ocean through Russia or Norway.

There are many lakes in Finland and this listing also includes several lakes through which the rivers flow or begin from. Due to the great number of lakes especially in the Finnish Lakeland, where watercourses tend to consist of chains of lakes rather than long rivers, some rivers with a large catchment area can also be quite short or there may only be a short rapid between large lakes, like for example Tammerkoski in Tampere.
