Father of All Motherfuckers (also known by the censored title Father of All... or Father of All M***********s) is the thirteenth studio album by the American rock band Green Day, released on February 7, 2020, through Reprise Records. Produced by Butch Walker, Chris Dugan, and the band, the album marks a complete departure from the band's traditional punk rock sound, incorporating garage rock elements similar to their tenth studio album, ¡Dos! (2012).

The album was preceded by three singles: "Father of All...", "Fire, Ready, Aim" and "Oh Yeah!". It debuted atop the UK Albums Chart and Australian ARIA Albums Chart, among others. Despite chart success, the album received polarizing reviews from critics and negative reviews from the band's fanbase, with praise for the album's brisk pace and energy, but criticism for its lyrics and runtime.
