Logan Armstrong is a fictional character from The Young and the Restless, portrayed by actress Deanna Russo.

Logan was introduced in June 11, 2007, when it was revealed that Nicholas Newman (played by Joshua Morrow), who was presumed dead in a plane crash, was in fact still alive.

Logan, a nurse who was on a hiking trip, had found a severely injured Nick and taken him back to her cabin (their whereabouts are still unknown). Nick awoke from his coma weeks later, still in the cabin.
