Publius Autronius Paetus was a politician of the late Roman Republic who was involved in the conspiracy of Catiline.
[1] Some sources claim that Autronius conspired with Catiline to murder Cotta and Torquatus on the day of their installation, January 1, 65 BC, but the plot collapsed when Catiline gave the signal before all the conspirators were assembled.
[2] Later, Autronius was implicated in Catiline's failed conspiracy of 63 BC,[3] and, after his old friend Cicero refused to defend him, he was convicted and sent into exile in Epirus.
Paetus's wife is not mentioned by name but since the speech Pro Sulla refers to him as a "propinquus" of the Claudii Marcelli it is possible that she was a Claudia Marcella or a Junia.
This is supported further by inscriptions of freedmen of his son Lucius Autronius Paetus's which are located in and around the monumentum familiae Marcellae.
