The pink tide (Spanish: marea rosa; Portuguese: onda rosa), or the turn to the left (Spanish: giro a la izquierda; Portuguese: virada à esquerda), is a political wave and turn towards left-wing governments in Latin America throughout the 21st century. As a term, both phrases are used in political analysis in the news media and elsewhere to refer to a move toward more economically progressive or socially progressive policies in the region. Such governments have been referred to as "left-of-centre", "left-leaning", and "radical social-democratic". They are also members of the São Paulo Forum, a conference of left-wing political parties and other organizations from the Americas.
The Latin American countries viewed as part of this ideological trend have been referred to as pink tide nations, with the term post-neoliberalism or socialism of the 21st century also being used to describe the movement. Elements of the movement have included a rejection of the Washington Consensus. At the same time, some pink tide governments, such as those of Argentina, Brazil, and Venezuela, have been varyingly characterized as being anti-American, prone to populism, as well as authoritarian, particularly in the case of Nicaragua and Venezuela by the 2010s, although many others remained democratic.
