Imperium is a 2006 novel by English author Robert Harris. It is a fictional biography of Cicero, told through the first-person narrator of his secretary Tiro, beginning with the prosecution of Gaius Verres.

The book is the first in a trilogy. The second volume, Lustrum (Conspirata for U.S. audiences), was published in October 2009. The third volume, Dictator, was published in 2015. Publication of the sequels was delayed whilst Harris worked on other books, including his contemporary political novel, The Ghost, inspired by the resignation of Tony Blair.

The book was serialised as the Book at Bedtime on BBC Radio 4 from 4 to 15 September 2006, read by Douglas Hodge. An abridged audiobook on compact disc is available, read by British actor Oliver Ford Davies. Unabridged audiobooks on compact disc are also available, read by Simon Jones and Bill Wallis.

A theatrical adaptation of the trilogy by Mike Poulton was performed by the Royal Shakespeare Company in the Swan Theatre, Stratford-upon-Avon in 2017, and transferred to the Gielgud Theatre in London in 2018. The two plays were directed by RSC Artistic Director Gregory Doran, with Richard McCabe as Cicero.
