María Patricia Arce Guzmán (born 6 May 1970) is a Bolivian lawyer and politician serving as senator for Cochabamba since 2020.

After studying high school and automotive mechanics, she graduated as a lawyer and later became a tax assistant in Chapare and coordinator of the Rural Patrol Mobile Unit.

[2] Arce was invited to be a candidate for Solidarity Civic Unity, which she rejected, and in 2015, Evo Morales offered her to run for mayor of Vinto, a municipality where she had lived for two decades.

[2] Within the framework of the 2019 Bolivian political crisis, on 6 November, Arce was lynched in public when a group of protesters entered the Vinto Municipality building to forcefully expel her under accusations of "counteracting" citizen mobilizations with miners, burning plus government facilities.

She was kidnapped by a mob and dragged down the street, being forced to walk barefoot for several kilometers and suffering various physical attacks when she was beaten, shaved, and sprayed with red paint all over her body.
