Crewman Donaldson was an engineer serving on board the USS Enterprise-D in 2368.

When Chief Engineer La Forge's enthusiasm about participating in the first soliton wave test was not shared by Worf and Data, La Forge tried to talk with Donaldson about it, feeling that as a fellow engineer, he might be more interested than they were. (TNG: "New Ground")

Donaldson was played by an unknown actor.
