Lucius Caecilius Iucundus (born c. AD 9,^[1] fl. AD 27–c. AD 62) was a banker who lived in the Roman town of Pompeii around AD 14–62. His house still stands and can be seen in the ruins of the city of Pompeii which remain after being partially destroyed by the eruption of Vesuvius in AD 79. The house is known both for its frescoes and for the trove of wax tablets discovered there in 1875, which gave scholars access to the records of Iucundus's banking operations.

Iucundus is the basis of the character Caecilius in the Cambridge Latin Course, a British series of Latin textbooks based around the life of Caecilius and his family. He is also the basis of the Doctor Who character Lobus Caecilius, played by Peter Capaldi, whose fate is given symbolic importance for the version of the title character later portrayed by Capaldi. He also appears as a minor character in the novel Pompeii by Robert Harris.
