Inside Man is the 152nd episode of the science fiction television series Star Trek: Voyager, the sixth episode of the seventh season. This continues the story arc previously established in Pathfinder and Life Line, Voyager episodes featuring the Star Trek franchise characters Reginald Barclay and Deanna Troi. Like Pathfinder this also has scenes with Paris's dad Admiral Paris. It further develops Barclay's character and introduces one of his romantic interests, Leosa. Barclay's relationship with his over-bearing commander on the Pathfinder project, Commander Harkins, is also further developed.

Dwight Schultz gets to act as two different characters in the same skin, as Barclay, and as hologram based on Barclay. Barclay (as Shultz) and his team from Project Pathfinder, including Admiral Paris also make another appearance in Voyager's series finale "Endgame".

Voyager receives its monthly datastream from Starfleet via the Pathfinder project, which has been helping Voyager find a way home from the Delta Quadrant. In the stream, they find the programming for a hologram and discover it is a simulation of Reginald Barclay, one of the Starfleet officers working on it. Holo-Barclay explains that Starfleet has found a way to return Voyager home through a geodesic fold between two red giants, but this will require special shield modifications and inoculations for the crew to survive the trip. The Doctor allows Holo-Barclay to use his mobile emitter as to supervise the work, and tries to be friends with him, but Holo-Barclay seems intent on his duty. Holo-Barclay even ignores the concerns the Doctor puts forward about the effectiveness of the inoculations, putting the Doctor on edge. The Doctor tells Captain Kathryn Janeway of his concerns, who orders a check of the Holo-Barclay program but finds nothing amiss. They continue to prepare the ship, while Holo-Barclay sends back reports included in Voyager's datastream.
