Milonia Caesonia (- 41 CE) was a Roman empress and the fourth wife of Caligula. Little is written about her, though she is described as neither beautiful nor young, with a reckless extravagance and uncontrolled wantonness, and that she was loved devotedly and passionately by Caligula. Some stories claim that Caligula would often parade Caesonia in front of his troops, and sometimes would parade her naked in front of select friends. Caesonia and her daughter, Julia Drusilla, were murdered hours after Caligula's assassination.
