Lucius Plautius Lamia Silvanus (ca 110 – aft. 145) was a suffect consul in 145.
He was the son of Lucius Fundanius Laemia Aelianus and wife Annia. According to the Augustan History, Silvanus married Aurelia Fadilla (b. ca 120), daughter of Antoninus Pius and Annia Galeria Faustina or Faustina the Elder. Their daughter Silvana (b. ca 120), married Marcus Annius Severus, a suffect consul, and they would be the parents of Fabia Orestilla (ca 160 – bef. 238), wife of Gordian I.
The Augustan History claims that Fabia Orestilla was a descendant of Roman Emperors Antoninus Pius and Marcus Aurelius through her father Fulvus Antoninus. Modern historians have dismissed this name and her information as false, as they believe his wife was the granddaughter of Greek Sophist, consul and tutor Herodes Atticus.
