Maisa Heloísa Juana Rojas Corradi (born 10 August 1972) is a Chilean politician, physicist, and climatologist[1] who has been serving as Minister for the Environment since 2022.

[3][4] Rojas was a postdoctoral fellow at the International Research Institute for Climate and Society at Columbia University in 2001.

[7] Rojas, along with Jennifer Morgan, led the working group at the 2022 United Nations Climate Change Conference that developed an agreement on loss and damage finance.

[8][9] In a mid-2023 interview, following one year as environment minister, Rojas stated that a major reason for entering politics was to prevent noted climate denier José Antonio Kast from becoming president.

Rojas also does not believe that present government institutions are equipped to deal with the scale of the climate emergency we face.
