Publia Fulvia Plautilla (died 211) was the wife of the Roman emperor Caracalla, her paternal second cousin.

The Fulvius family was of plebeian origin, came from Tusculum, Italy and had been active in politics since the Roman Republic.

[2] According to Cassius Dio, Plautilla had a profligate character; however, scholars view this as most likely being a claim driven by propaganda.

[2] They were treated very harshly and were eventually strangled, possibly on Caracalla's orders after the death of Septimius Severus on 4 February 211.

[10] The Solinjanka or Salonitanka, meaning "woman from the city of Solin (ancient Salona)", one of the most important Roman portraits found in Croatia, is believed to depict Plautilla at a young age.
