The Collor Plan, is the name given to a collection of economic reforms and inflation-stabilization plans carried out in Brazil during the presidency of Fernando Collor de Mello, between 1990 and 1992. The plan was officially called New Brazil Plan, but it became closely associated with Collor himself, and "Plano Collor" became its de facto name.

The Collor government, also referred to as the Collor Era, was a period in Brazilian political history that began with the inauguration of President Fernando Collor de Mello on March 15, 1990, and ended with his resignation from the presidency on December 29, 1992. Fernando Collor was the first president elected by the people since 1960, when Jânio Quadros won the last direct election for president before the beginning of the Military Dictatorship. His removal from office on October 2, 1992, was a consequence of his impeachment proceedings the day before, followed by cassation.
