Lucius Mindius is an unattested Roman Aristocrat who lived in the
Roman Emperor Trajan, becoming her second husband. Matidia was previously widowed from her first marriage to suffect consul Lucius Vibius Sabinus, who left Matidia a daughter Vibia Sabina
.
In 85, Matidia bore Mindius a daughter called Mindia Matidia, commonly known as Matidia Minor or Matidia the Younger. Like Matidia's first marriage, Matidia's marriage to Lucius Mindius was short-lived. Shortly after the birth of Mindia Matidia, Lucius Mindius had died. In 86 Matidia married the consul Lucius Scribonius Libo Rupilius Frugi Bonus.
^The epitomator of Cassius Dio (72.22) gives the story that Faustina the Elder promised to marry Avidius Cassius. This is also echoed in HA"Marcus Aurelius" 24.
