The Green League, shortened to the Greens, is a green political party in Finland. Ideologically, the Green League is positioned on the centre-left of the political spectrum. It is a reformist party and it is supportive of feminism, animal rights and green liberal ideas.

Green politics, or ecopolitics, is a political ideology that aims to foster an ecologically sustainable society often, but not always, rooted in environmentalism, nonviolence, social justice and grassroots democracy. It began taking shape in the western world in the 1970s; since then green parties have developed and established themselves in many countries around the globe and have achieved some electoral success.
