A Transporter Chief is a title attributed to characters featured in the Star Trek multimedia franchise. They are in charge of operation and maintenance of the transporter controls on a starship. Transporter chiefs and transporter technicians are members of the Starfleet Corps of Engineers and serve out of the Engineering department on whichever vessels they are stationed on.

Basically, the Transporter Chief stands behind a computer console, which is facing a teleportation pad and programs coordinates for point to point transportation of matter. The process involves molecularly breaking down bonds of matter, converting it into a stream of transferable data and reassembling the matter, including biological matter, at a predetermined destination point. The transporter chief is also responsible for recalling matter or life forms from the destination back to it's point of origin.

On the original Star Trek television series, the Transporter Chief was Montgomery Scott, who was also the Chief Engineer on the USS Enterprise. In the event that Mister Scott's expertise was required for an away mission, another engineer would step in to take his place.

On Star Trek: The Next Generation, the transporter chief aboard the USS Enterprise NCC-1701-D was Miles O'Brien. In situations where O'Brien was unavailable, Chief Engineer Geordi La Forge stood in his place.
