Karl-Petter "Kålle" Thorwaldsson (born 26 December 1964) is a Swedish union leader and politician who has served as Minister for Business, Industry and Innovation since November 2021.

He later became a political advisor at the Prime Minister's Office and head of information at the Social Democrat Party before becoming ombudsman at the trade union IF Metall.

[6] This strategy of going to great lengths to keep out independent unions from being able to mobilize members in industries where the three confederations have agreed internally to delineating agreements about organizing rights has been widely criticized both outside and inside the LO movement, by legal experts and grass-roots alike.

It faced criticism from advisors of the U.N. Human Rights Council,[10] as well as resistance from local Sami population backed by environmental activists including Greta Thunberg.

[11] During the debate preceding the decision Thorwaldsson said in an interview: "I, we in the Social Democratic Party love mines",[12] which became infamous among the activists opposing the project.
