The Department of Temporal Investigations was a section of the United Federation of Planets, tasked with ensuring that time travel events which occurred under Federation jurisdiction were handled within guidelines established to prevent contamination of the timeline. James T. Kirk had the biggest file on record in the Department, with seventeen recorded temporal violations.
In 2373, two investigators from the Department, Dulmur and Lucsly, arrived on station Deep Space 9, to debrief Captain Benjamin Sisko on a recent time travel incident, wherein Klingon spy Arne Darvin utilized the Orb of Time to take the USS Defiant back in time to 2268 in an attempt to assassinate Captain Kirk. After the interview, Dulmur intimated to Sisko that he did not believe that the actions of his crew while in the past constituted a major violation of regulations regarding time travel.

- In the novel A Pocket Full of Lies, it is revealed that, following the events of the Year of Hell, the Krenim of the new timeline have established a variation of the Department of Temporal Investigations known as the Krenim Temporal Defense Agency. However, in contrast to the DTI's goal to preserve the current history, the Agency's goal appears to be to use time travel to subtly ensure Krenim supremacy in the present timeline. As a result of this goal, they altered a timeline where their past enemies, the Rilnar and the Zahl, lived on a peaceful near-utopian planet, in favour of a timeline where the two were engaged in a protracted and pointless conflict on the same planet, because the peaceful timeline restricted Krenim expansion.
- The department features in the Star Trek Online novel, The Needs of the Many.
