Sean Penn's actress wife just waved the white flag on their union ... because she filed for divorce after just over one year of marriage.
Sean's wife, Australian actress Leila George, filed divorce docs Friday in Los Angeles County Superior Court ... according to online records.
Sean and Leila, the daughter of actor Vincent D'Onofrio, tied the knot in July 2020 during the height of the pandemic ... getting hitched in a lowkey family wedding at their home.
They started dating way back in 2016 and did not have any children together.
It's unclear what led to the split.
