Death on the Tiber is a historical crime novel by British writer Lindsey Davis, the twelfth in her Flavia Albia series.

[5]: xi  The list of characters includes Marcus Didio Falco ("one-time hero; has he still got it?")

and Helena Justina ("his wife, an absoluter heroine") from the Falco series, vigiles from seven cohorts, and members of five underworld gangs.

[5]: xiii–xvii  Davis has said that the plot involves a corpse dredged out of the Tiber, the "ever-warring gangster community", "the failings of the various public bodies who are supposed to tackle crime and threats to the community" and "a very elaborate joke about crime writing".

The cover of the first UK hardback edition shows a barnacle-encrusted vase on a river-bed with blood flowing out of it.
