Connor Block was a male human serving Starfleet in the 24th century.

By late-2385, Block held the rank of ensign and was assigned to security of the Newton Outpost. In December, Block 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.
