Marcela Cubillos

Marcela Cubillos Sigall (born 2 February 1967) is a Chilean lawyer, politician, and constitutional delegate, widely known for her active role in her country's political and institutional debates over the last two decades.

Previously affiliated with the conservative Independent Democratic Union (UDI), she has held multiple public offices, including Minister for the Environment and Minister of Education during the second administration of President Sebastián Piñera.

In 2021, Cubillos was elected to the Constitutional Convention, becoming one of the most visible voices of the Chilean political right in the body tasked with drafting a new constitution. Known for her firm positions on education policy, environmental management, and national unity, she consistently defended free market principles, traditional institutions, and the unitary state model, often clashing with the more progressive and plurinational proposals advanced by the Convention’s left-wing majority.

Her presence in both executive and constituent roles has made her one of the leading female figures of Chile’s contemporary right, as well as a polarizing figure in public discourse. Following the rejection of the proposed new constitution in the 2022 referendum, she has continued to influence conservative strategy in political and academic spaces.
