Petals for Armor II is the second extended play (EP) by American singer-songwriter and Paramore frontwoman Hayley Williams. It was released on Atlantic Records on April 21, 2020, as the second in a series of releases in the Petals for Armor era. Williams explained the inspiration behind its title is due to her belief that "the best way for me to protect myself is to be vulnerable."

Petals for Armor II was produced by Williams' Paramore bandmate Taylor York and was written throughout 2019 during Paramore's hiatus after touring in support of their fifth studio album, After Laughter (2017). The lead single, "Roses/Lotus/Violet/Iris", was released on March 19, 2020.
