Elise Ehrenreich was a female human serving Starfleet in the late-24th century.

By late-2385, Ehrenreich held the rank of ensign and was assigned to security of the Newton Outpost. In December, Ehrenreich was part of Lieutenant commander Selten's team that attempted to stop the Jem'Hadar-Ascendant Link from escaping the outpost, though the team was unable to do so.
